Optical Illusions and Visual Phenomena

Filed under: Stuff — paulcook @ 7:57 pm


A huge collection of visual illusions: Optical Illusions and Visual Phenomena.

One of my all-time favourite illusions:

Optical illusion

Yes, the squares A and B are EXACTLY the same colour. The human visual system does so much pre-processing that it recognises that the cylinder is casting a “shadow”, and edits the perceived image such that you see a colour much nearer the colour that would have been there, were it not for the shadow.

  1. I can normally convince myself that these optical illusions are indeed illusions, but this one stumped me. I actually had to break out The GIMP and break it down into A and B to convince myself that they were actually the same shade of gray.

    One of my favorite classes at Rice, CAAM 415 — Theoretical Neuroscience, actually looked at how some of the optical signal processing is done, although the most complex thing we looked at was how the brain interprets horizontal vs. vertical lines vs. diagonal lines.

    The truly amazing thing is how much of the processing is learned rather than genetic. We genetically have the ability to learn how to interpret images correctly, but it is possible to block development of these things. For instance, someone who is blind from birth will always be blind if you are able to give them sight after a certain age. The time at which the brain is capable of learning how to see will have already been passed, so the signal might get to the brain, but the brain won’t know what to do with it. There is actually an interesting experiment with cats where they are raised in an environment with only horizontal and vertical lines (no curves, etc.). They are then placed into an environment with curves and they proceed to bump into things like balls, curved walls, etc. The first layer of cells in the retina detect the light from the curved objects, but that’s as far as the signal goes.

  2. Have you ever read Oliver Sacks’ The Man Who Mistook His Wife for a Hat, or one of the sequels? They’re fascinating collections of stories of people with very unusual mental or perceptual problems. A number of the stories have to do with visual processing — for instance, how different eyes function in people who’ve had the two halves of their brain separated. Amazing stuff!

  3. Looks wonderful, it’s now on my (very lengthy) list of books to read. One of my favorite mental/perceptual disorders is the one (can’t remember the name and don’t want to take the time to look it up) where you “taste” shapes/colors/sounds, “hear” colors, etc. Essentially, something gets miswired so that there are crossovers between your senses. There is a crossover that pretty much everyone has between taste and smell (notice how you can’t taste food as well when you have a cold?), but the crossovers in this disorder are much more bizarre and pronounced.

    Comment by Adam — 27 Sep 2005 @ 12:54 am

  4. Well, as far as I remember that was one of the disorders in either this book, or one of the others by Sacks. They make for amazing reading!

  5. Some really interesting illusions in that link. The one with the purple/green dots really blows my mind. Here are some more (sort of related) links that I found a while ago:

  7. The artist Kandinsky had that disorder, it’s called synesthesia. He painted symphonies. The video game Rez is based on this perceptual disorder.

  8. Rez is a very interesting game. I suck at it.

  9. I AM SOOO PISSED. I DO NOT GET THIS AT ALL. Don’t try to cover it up with some weird scientifical explination because we all know that they ARE NOT the same shade of gray !!!

    Comment by VERY MAD — 2 Apr 2007 @ 8:51 pm

  10. Well, unfortunately they are — as any graphics software can easily verify. It’s really amazing how completely your eyes deceive you. Even with knowing that they’re the same colour, I still can’t force my eyes to see them as the same.

    Comment by Anonymous — 29 Apr 2007 @ 1:14 pm

  15. if they are the same because of the shadow then why is it when you scroll down and dont see the cylinder or the shadow they still appear different colours?

    Comment by cwade — 29 Apr 2007 @ 1:31 pm

  16. I don;t buy it -I’v tried putting the image in MSPaint as suggested above - doesn’t matter. THis is a hoax!

    Comment by skeptical — 29 Apr 2007 @ 1:38 pm

  17. Boy, people will believe anything! I’m actually mad at myself for the time I spent checking this one out. Trust your gut people…they are obviously not the same shade and can be proven by simply covering up all other squares on the screen. You might need some help, but we got a kick looking at it!

    Comment by beckearly — 29 Apr 2007 @ 3:10 pm

  18. Seriously. The whole point of an optical illusion is that it tricks your eyes. Thus, beckearly, you can look at it all you like, and still see the illusion — trust me, I have. However, the fact remains that they really ARE the same colour. skeptical, as you discovered, MSPaint shows that they are the same colour. beckearly, with just a little more effort, and any sort of graphics program, you can prove it too.

    And yes, even after you see in a graphics program that they are the same colour, you will STILL not be able to force yourself to see this fact. It really shows that things like shadows are processed very early in the visual process — indeed, so early that no amount of conscious knowledge can change what your eyes think they see.

    Let me repeat myself again, to make ABSOLUTELY sure: the two squares ARE the same colour. Amazing, but true — try it yourself in a graphics program.

    Comment by paulcook — 29 Apr 2007 @ 9:46 pm

  19. Your picture is soooo cool. I never thought that those two tiles could be the same color!!!!!!!!

    Comment by Dennis — 3 May 2007 @ 9:38 am

  20. Eggs and ham are my favorite colors!! Crayons taste like them when they are cold.

    Comment by Eggmaniac — 3 May 2007 @ 9:42 am

  21. I SEE IT! I didn’t believe it at first. But if you stare at “B” long enough, you see what’s going on. It begins to darken and it is, in fact, the same color as “A”. Keep trying people…it’s not a hoax, I swear!

    Comment by Matt — 6 May 2007 @ 5:58 pm

  22. It’s true. I was a non-believer until I copied the image, opened it in PhotoShop and sampled both “A” and “B.” They are EXACTLY the same color. Put them side by side and you’ll see. Before I did it, I was going to post on here, “Nice hoax! You are going to drive lots of folks crazy!” Now I know it’s true. Your brain can really mess with you in contextual cue set-ups like this one. Makes you wonder how many other things in life are like this. Prior to doing the PhotShop thing, I would have bet my life that the two squares were different colors, and I would have lost!

    Comment by Joe — 6 May 2007 @ 6:46 pm

  23. THIS IS NOT TRUE THAT SQUARE A AND B ARE THE SAME SHADE I WILL SHOW YOU HOW TO TELL. YOU GET PAPER OR SOMETHING TO COVE MOST OF THE PICTURE I USED TWO ENVELOPES ND LEAVE A LITTLE SLOT ABOUT 1CM WIDE ENOUGH TO SEE SQUARES A AND B WITHOUT SEEING THE SHADOW OR CYLINDER. THEN U WILL SEE THEY ARE DIFFERENT. THE COOL THING IS THERE IS STILL AN ILLUSION IN THE PICTURE WITH SQUARE B AND THE SECOND UP FROM THE BOTTOM RIGHT WHICH DO HAVE THE SAME SHADE. I THINK THEY PLACED THE A ON THE WRONG SUARE. SO IT IS STILL COOL.

    Comment by JOEY — 6 May 2007 @ 7:45 pm

  24. They are almost the same colour as i have verified in my macromedia fireworks program. To say they are the same exact color is not true there close but not an exact match. I think this one of the worse illusions i have seen.. But trust me there are a lot of other bad ones out there.

    Comment by Johnny — 6 May 2007 @ 8:03 pm

  25. This thing totally freaks me out..I tried covering up parts of the design, taking off my glasses and squinting so I could barely see it and I said Bull*** this is not an illusion..I printed it out on paper and I still said Bull***..Then I took scissors and cut out the B square and laid it on the A and they are the same shade…Totally cool…

    Comment by Terry — 6 May 2007 @ 8:49 pm

  26. This is really wild. It took me a while to understand what people were saying about how to look at squares A and B to see their “absolute colors,” but finally I took the image to Paint, and picked up the color from A with the eyedropper, made a small box and filled it with the paint can tool — then did the same with B… and just as everyone who does test it says, they are the same — or close enough.

    But what really got me was that I then cut out a square from the little B box that I’d made and moved it to the original B square — I couldn’t believe it — the square changed color while it was moving! And this works whether you leave white space around the cut-out or cut it so the color bleeds to the edge.

    Thanks for a real mind-bender!

    Comment by Allison — 7 May 2007 @ 1:07 am

  27. Thanks for all the comments!

    Joey: Nope, the letters are in exactly the right place. Terry had a good idea of actually printing the image and cutting out one of the squares — then you really can compare the colours.

    Johnny: There is some distortion caused by the JPEG compression that you might be seeing. But the base colour of the squares (exactly #6B6B6B in hex notation) is EXACTLY the same. Not close, but EXACT. Also, I’m not sure what you meant at the end of your comment.

    Comment by paulcook — 7 May 2007 @ 11:43 am

  28. A and B aren’t the same color. There are two colors on the block. B is the lighter shade, and A is the darker shade. The cylinder just makes B look a bit darker.

    Comment by Jess — 29 May 2007 @ 2:25 pm

  29. Thanks for your comment, Jess. However, as you can read above, A and B are in fact exactly the same colour — your visual system “subtracts” some darkness from B due to the “shadow”, so that you think it is lighter. They are in fact the same colour.

    Comment by paulcook — 29 May 2007 @ 2:48 pm

  30. A and B are the same color.

    Comment by Anonymous — 11 Jun 2007 @ 6:54 pm

  31. no the point of the illusion is the title the “square a” and “b” because the letter b is the same colour of the square around a,, it has nothing to do with the cylinders shadow

    Comment by hr — 21 Jun 2007 @ 8:21 pm

  32. IT IS THE SAME COLOR, save this thing to your comp, open it with adobe or even paint and use the “eyedropper tool” or pick color tool and draw something with both shades, you’ll see that it IS the exact same color.

    Comment by Joe — 24 Jun 2007 @ 2:03 am

  33. hr: Yes, good, thanks, that’s wrong. The square around “A” is the same colour as the square around “B”. It has everything to do with the cylinder’s shadow.

    Comment by paulcook — 26 Jun 2007 @ 3:08 am

  34. It is the EXACT SAME color. Put the image on paint use the cut out option and take a sample from each. put it to the side and you’ll see that it is the precise same shade.

    Comment by Simple — 4 Jul 2007 @ 8:00 pm

  35. it truly is tru. honestly it is AMAZING! plzz it is not a hoxe go into paint and cut the 2 squars out and bam! same shade… try it.

  39. Hey! These illusions were pretty cool. I like the one were you see Jesus though. (Im not sure if you have that one i think i saw it on a diffrent website). Pretty cool moving ones here though!! Pls add more, ever so entertaining! I could look at illusions 4 ages!

  42. get a 2 pieces of paper cut a small whole in it. about 5mm. put it over both squares so all you see is part of the square. now compare. the same colour.
    Brilliant

    Comment by Anonymous — 8 Sep 2007 @ 9:51 pm

  46. I couldn’t believe it at first, but both squares really ARE the same: both R107 G107 B107 as can be checked in Photshop.
    But the illusion is, in my opinion, not specificly related to the cylinder shadow, nor to the white A or the black B (although they do enhance the illusion).
    Even when I made a close-up in Photoshop so the cylinder was not visible, and deleted the A and B, the squares still looked as if they were of a different color. It is all because the surrounding colors are gradient shades of grey.

    Comment by jennie e — 27 Nov 2007 @ 6:45 am

  58. ok for those of you who r skeptical, they really are the same color

    i didnt believe it at frist either but try printing it out (color printer or not) and then cut out the b square and lay it over the a square. They are the same color

    or

    copy the picture and go to MS paint and paste it and use the eye dropper thing and click on the b square. Its the same color as the a square

  64. RUBBISH! I cut holes in a piece of card and heldit over the screen and guess what A is a darker shade than B! (If you believe they’re not then you will believe A and B in this email are actualy the same letter!!)

    Comment by Jessica Moody n co. — 12 Jan 2008 @ 2:14 pm

  65. It works! I used a graphics program, the reason why if you print the picture out and then place the two pieces together and they appear different is because you have introduced an intermediate process. If you try it on a design program then you can see your brain ‘change its mind’ on what colour it is. I placed the colours next to each other and it worked. If you print it out, you have taken the colours out of their context and the brain no longer understands the shadowing etc… and will just see two separate colours, you need the cylinder and the shadow still to be present in the image whilst you edit it for it to work. :)

  75. Can I just say, people feel free to be sceptical, feel free to tell people that you don’t believe it, but why resort to insulting? If you’re so sceptical , why are you bothering to post? And all you people who just post, ha you guys are so stupid, of course it isn’t the same colour. Try it. You’ll see for a fact its true, you just can’t comprehend the power of the mind, its not possible for someone to do that. This is seriously waird though, because if you drag it, you can see it changing colours. *Baffled* O.O

    I took the original image and put it into MSPaint. I took square A and painted an A, took a drop of B and painted a B. I did this 2x because I couldn’t believe it. I then did it a 3rd time and painted a square across squares A & B and labeled them. As you can see they are the same colour. WFT?

    Without eyes you are blind right? Wrong. Some blind people can see better then us because they use their mind, ears, touch and smell (some use taste, but thats just dirty. If you know what I mean lol). If you can’t see that they are the same colour, close your eyes and open your mind!

    there’s the original picture plus the «solution» that proves the fact that it IS the same color with two connecting stripes of the same shade

    Comment by fairy — 5 May 2008 @ 10:37 am

  86. Wow people.
    They ARE the same color.
    It just doesn’t appear that way because the shadow darkens ‘B’.
    If you cover all the squares, that doesn’t get rid of the shadow.

  108. ok ok how on earth can that be true? the green cylinder must be an exuse for it to be more credible and believable but remove the shape and maybe the letter’s and then maybe we could be faced with something far more credible.

  111. Its funny how we visually process information, unless you have editing software you will not be able to see why this is true, trust me to the naked eye you will not see it,

  115. The coolest mind-blowing part is having actually printed it out and sliced the two squares together and now KNOWING they are the same my mind still refuses to let me see it that way on the original. BTW all the skeptics are doing is proving how incredible an illusion it is

  118. i have no idea what you guys are talking about because i didn’t want to read all that, but i think that they’re not the same color, and they’re just telling you that to make you belive something that’s not true!

    Comment by sara — 9 Sep 2008 @ 5:42 pm

  119. Good grief! And that is exactly the problem — somehow, it’s become acceptable to form an opinion based on nothing, and then stick to it, and not even read the counter-evidence when it’s right in front of you.

    Yes, they are the same colour, and no, it’s not acceptable to just form your own opinion on the truth and then stick to it. Getting this right would have prevented such costly mistakes as the Iraq war, not to mention the continuing lack of action of global climate change.

  127. lol its funny but omg its true i tested it with paint, its crazy, the painter/artist who drew this is a true illusionist!

    Comment by lol — 8 Oct 2008 @ 11:25 am

  128. Okay people, let’s get something straight. First of all, you have no right to say that these squares aren’t the same color if you haven’t actually TESTED it. There is a very simple way to test it. Simply right click the picture, then open paint and to go Edit-Paste. Then, erase EVERYTHING but the A and B squares. If you do this correctly, you will realize that the two colors are indeed the same. I was one of the skeptics, but once I actually checked, I was astonished.

  151. This is a fact, and I can show all of you how to prove it. Copy the image, and fold the image, or cut it out. Hold said image up against the other, and you will clearly see, with out a doubt, that the images are the same.

    Comment by Lupercus184 — 12 Jan 2009 @ 3:26 am

  159. OMG, ppl, I know you don’t believe it—I didn’t either. They look different. But I cut them out and they really are the same. Just try it for yourself, you’ll feel stupid for being skeptical.

    P.S. I’m an American and I don’t understand the gray/grey thing either… My computer says gray is correct so I go with that.

  169. I took a picture of only the 1 A and the oneB and made a slide show. they’re not the same color. I do not get this illusion. Normally I can see the illusion but this one….. I dont know. I wish they would show one without the shadow so I can at least get it a little bit.

  217. IT IS TRUE!
    1. edit the picture in paint.
    2.select the crop tool (top right)
    3.crop a small part from square “A” and move it off to the side
    4.crop a small part from square “B” and move it so both selections are touching
    I didn’t believe it either.

    Comment by its true!! — 11 Jun 2009 @ 6:10 am

  218. This is not true. I don’t think that two different colors are the same if the human eye doesn’t see it. I know it sounds dumb, but that is what changes color. When the color is in that form, they are different colors, but when they are broken up, and the colors are shown exactly alike, then they are alike, but colors aren’t always the same color.

  220. For the non-believers that this optical illusion isn’t fake.
    Several people gave a method to control the equality between A and B.
    Another method is to download a good freeware color utility and measure both colors: e.g.
    Een other impressive color illusion is with real colors, not just gray.

    .47. Rubik’s Cube Optical Illusion

    Of interest to us in this illusion are only the central pieces of each of the three visible sides. Two sides are lit and have a brown tile in the middle. The side in shadow has a yellow tile in the middle.

    Or does it?

    Use the colour picker in any imaging software and you’ll find all three central tiles are exactly the same colour.

    Comment by Eric — 18 Jun 2009 @ 7:18 pm

  221. I did something wrong with the above comment.
    The first link goes to the freeware color picker site. Download and use it to measure the colors which will show they’re equal:

    Comment by Eric — 18 Jun 2009 @ 7:23 pm

  222. Colors in itself DO NOT EXIST. Visible light are waves in the range of +/- 380 to 780 nanometers. Hence it seems that there is a fixed relationship between wavelength and the colors we see. What we see are these wavelengts which are reflected from the object. Our eyes and brain interpret these wavelengths as being certain colors.
    However our brain interprets this incoming information in context of other information it receives (the neighboring colors and light).
    Hence a color just isn’t a physical object or thing. It is made in our brain resulting from the incoming information interpreted within a context.

  231. How did some of you manage to copy images into your comments? I’d like to put an image into mine & prove just how many squares are the same color. Not two… not four… six squares total! …Ok no, 5 & a quarter. If I can get an image on here, I will prove it. There will be squares labeled from A through F.

    Comment by Woody — 5 Aug 2009 @ 10:02 pm

  232. If you import this picture into Paint, and then use the Pick Color tool. You will then see that the squares are infact the same colour.
    This is brilliant! This is a proven illusion. Check it for yourself!

  234. I just couldnt believe my eyes as many other ppl probably felt after seeing this, so i went on Paint to have a look for myself and saw that it is true that they are the same shade of grey.
    But does the fact that the Color of the “A” on the “A” square is white while the Color of the “B” on the “B” square is a darker shade of Grey. does this make a difference on how our eyes see this illusion?

    Comment by benjii — 10 Feb 2010 @ 2:50 am

  253. It is with great concern that I read the comments in this blog. Most especially those of the webmaster. They seem to be presenting a very one sided view of the debate. While I am happy to let those who wish to believe the Theory of Color Sameness (and remember, it is only a theory!), it seems irresponsible to not allow equal space to those supporting the Theory of Color Difference. By dismissing the Same viewpoint out of hand, the webmaster is trying to tell us how we must think!

    Let’s review the arguments:
    1. The claim that the evidence unanimously supports the Theory of Sameness is blatantly false. Take for example the findings of beckearly (#17) or JOEY (#23), amongst many others. The results of those who have researched the matter are clearly divided on the issue.

    2. Many of the proponents of Sameness seem to have not appreciated the theoretical complexity of the issue. The arguments of hr (#31) show that it is not nearly as simple as saying “block A same color block B QED”. The webmaster (typically) has no answer to hr, but merely restates the Same hypothesis in the hope that bluster will be confused for rational argument. In fact, through the debates, the Same crowd have barely addressed the lettering issue at all!

    3. The webmaster himself admits that there is “distortion caused by the JPEG compression”. But this is conveniently “forgotten” by the familiar Same voices …

    4. Genesis 1:4-5 states “…and God divided the light from the darkness. And God called the light Day, and the darkness he called Night.” The Bible is pretty clear about what we should be believing here, folks.

    In summary, what we have is an improbable, contrary to scripture, “Theory” being forced upon us by the Webmaster. Further to this, they are implying that this is the obvious, unanimous conclusion of research (much of which is now discredited, I might add), ignoring the fact the debate is still raging, even amongst those who have conducted the research. Consider also the fact that the webmaster has a vested financial interest in supporting the Theory of Sameness (remember that more traffic = more income, thanks to the Google adds, and who is going to visit a site that has an optical illusion that is shown to be rubbish?). I am happy for you to believe whatever nonsense you want to, but don’t try to tell me how to think!

    My advice is stand write to your Senator to stand up against “Colorgate”. Demand that equal weight be given to the Theory of Color Difference.

  280. If you go on Untitled - Paint on your computer and cut out the B square and paste if somewhere else, it’ll be exactly like the A square. I didn’t believe this either till I tried it…

  281. What’s freak is if you go on Untitled - Paint on your computer, paste (don’t cut) out the B square (be sure not to get any other colours) and paste it onto the same already open picture and move the pasted B square under the shadow to where the other B is and out of the shadow again, the square changes colour, it’s frekin’ amazing!!!

  282. This is really amazing I had to cut and move in photoshop to make sure it’s true. I have done some optical illusions using forced perspective: looks like that:

  286. Confirmed, are same colour.

    First, I colour picker in photoshop. IDENTICAL (Even though its a JPEG). Then, I used brushes to create a line between the two boxes. The line seemed to start changing colours around where the shadow started. finally, I removed everything around the objects and placed them next to each other. SAME COLOUR.

    This concludes my “U GOT P0WNZ0R3D” broadcast for today.

  287. Cool! they are the same shade of gray. I cropped both squares in photoshop and it turned out to be exactly the same.

    Comment by tgf — 7 Nov 2010 @ 7:20 pm

  292. tgf… To be convinced do as follows:
    Copy the image to paint and erase everything but a piece of square A and a piece of square B, then put the pieces together and you’ll SEE they are the same shade of grey… I had to do so myself to realize they were the same…

    Comment by immy — 1 Dec 2010 @ 9:41 pm

  299. i do think they are the same colur but dont argue! some pll eyes work in different ways. if a person has less of one sense they have more of another. the could work both ways. this is a optical illusion and it all has a reason. you have a right to believe whether it is true or not true, but dont let anyone force you on that disicion.It could both be right. but stop swearing at each other ok?

    Comment by immy — 1 Dec 2010 @ 9:46 pm

  300. grey is grey and colour is colour not color or gray

    Comment by immy — 1 Dec 2010 @ 9:47 pm

  301. Okay all you people that say “oh it aint the same shade. yesss it issss the f*@% blocks are the saem color no the letter b and square a yer dumb. its the squares there the same. cut it out do whatever. Im telling ya there the same dude

    Comment by Jim Bob — 8 Dec 2010 @ 6:34 pm

  302. Wow ok, first of all, the only reason A and B look a different color is because there is a darker shade of Grey in the squares next to B. This creates an illusion because your eyes will be able to spot the difference between the two colors. They added the shadow to make you see it as a shadow and make moar sense…

    Comment by Deviousxbob — 13 Dec 2010 @ 7:23 pm

  303. @222 Yet we call it color and it exists, you fail.

    Comment by Deviousxbob — 13 Dec 2010 @ 7:27 pm

  304. Most amazing illusion i’ve even seen, it true 100%, i’ve cut the both boxes on photoshop and brought them together, oh my GOD, what happend to my eyes, I can’t recognize the boudary!

    Comment by Noman — 20 Apr 2011 @ 8:10 pm

  305. Nice Illusion. I thought it was fake at the beginning till copied the image and checked the RGB of each square. Surprisingly, they are the same.
    To make sure of it, copy a piece of both squares and place them next to each other on a white background, you’ll see the difference.
    Cheers!

    Comment by Mak — 29 Apr 2011 @ 9:16 am

  306. This is too cool…I cut out the squares and put them together…same color. I do not understand the non-believers when it is so easy to prove they ARE the same color. MSPaint works also but I being a former non-believer even with paint as proof had to resort to the scissors method :-)

  307. nice illusions i also thought it was fake

    Comment by jakky — 19 Nov 2011 @ 5:08 am

  308. according to the pattern on a chess or checkers board it is a different color. BTW you keep spelling color colour!

    Comment by Gavin — 21 Jun 2012 @ 2:19 pm

  309. Thanks Gavin! Yeah, “colour” is the international (British, South Africa, etc.) English spelling — like honour or centre. Colour, though, is a particularly tricky one, as most programming languages use “color” in the names of variables for changing colours. Tricky.
