An optical illusion on colors, take note of the colour of background A and background B, the Grey color of both A and B appears to be different. One slightly darker than the other, or so it seems to be. Is it really different in term of tone?
The truth is, both A and B are of same color, take a look at the Grey strip that run across both the checker board boxes. Our mind is playing tricks with us.

May 11th, 2008theyre really not the same. if u punch two holes in a piece of paper and hold one hole up to each square, the a one is darker. im not even kidding. try it
lora
May 16th, 2008this is totally wierd. do they change the colours or not? who cares about holes in paper anyway. it just ruins the paper.

May 22nd, 2008This is actually true, people. On Paintshop, if you select the dropper tool and hover it over each square, they have the same R, G, B numbers and the same shade of grey even appeares at the side. Also, what’s scarier is when you select each square and paste them onto a seperate image next to each other. Same shade! In the original image, they look different because of the shading creating by the cylinder. Scary stuff.

June 20th, 2008They are the same colour, get the dropper tool on paint, select one of the squares. Now try and draw on the other one, nothing comes up because they are the same colour.

September 3rd, 2008Dammit! It can’t be, but it IS. Photoshop doesn’t lie.

September 10th, 2008just save the first picture and open it with paint.. then use the dropper and draw on the other square.. its the same color.. the colors around square A is brighter then A so it makes A look darker.. but if you just take out everything else besides A and B.. then they look exactly the same color
pretty simple

September 12th, 2008they ARE THE SAME i didn’t believe it at first but i copied and pasted the pic into paint and grabbed the colour. Seriously try it its f’ing weird!!
ivona
October 21st, 2008they are the same!!!

aaa
November 8th, 2008They are both the same
Mia
November 9th, 2008They really are the same. If you print it out, cut out the two squares and put them side by side, they are the same. I did it!
emmanuel
November 19th, 2008ahh the miracles of the human eye and brain. the squares are the same tone and color. you know there are many great artists who understand and use color and tone just as magically. check out Gauguin friends. google search his name and view the images. then find out if your local museums have any of his originals and go see them.

November 27th, 2008seriously they are the same colour the onli reason the B is darker is due to the shade being provided from the cylinder…. dont you people look or think outside the box, i mean why else would the cylinder be there… you must be pretty ignorant and/or mentally retarded not to notice it open your mind people do your own thinking and as for the people using paint and photoshop you people need to have sex cause you have nothing better to do with your time then play on paint and/or photoshop
please
turtle…..
Errr...
January 14th, 2009this is plane shit. OMG so how can they be the same. Put your hands were the Fat lines arwe then you’ll see they are not the same colour. DUH . DimWitsss!!!!!!!
Errr... Is stupid
February 27th, 2009Actually they are the same. Dimwit….(who says that?) anyways copy the image now. then go into paint and paste. use the color sample tool. the thing that looks like a syringe almost. take the color of the background of A or B (it dosnt matter because they are the same) then paint on the other block ex: if you take the color from the background A paint over the actual letterB. and vice versa, notice how the color from the other block will erase the other letter. (color from background of A will erase the letter B) Because the color is the same….now STOP SAYING THEY ARE NOT THE SAME BECAUSE THEY ARE!…..
Dimwittsss!!! hahaha

French Soldier
June 14th, 2009It is obviously the same color, skeptics are simply wrong.
Cover the sides of the screen with an object on the first image and you’ll understand.
You Guys Are SADDD
June 30th, 2009I do agree with people who said Background A has gotten much lighter than the one without the compared bar. Okay, it’s not that I don’t admit optical illusions don’t exist. But if all you’re proving on is by Photoshop or Paint, I’m going to have to say, this is pure bullshit. Because paint and photoshop means shit to me, you can always create bugs, no matter how you click on the thing with the syringe, it’ll give you that color. So I do think this is quite bullshit, but who knows, whoever mentioned about cutting it out and putting them sideway saw that they’re the same color could be right. But it is pretty obvious that Background A is much darker than Background B in Figure 1, but in Figure 2, Background A noticeably lighten up, and the Bar that compares the two was contrasted from light to dark from bottom to top, respectively. So I do think this is pure bullshit.
I'm sorry but YOU are sad.....
July 6th, 2009The two colors (A and B) are the same. And it’s amazing to me how many people will get on here and call someone else a “dumb-ass” or some other thing like that because they don’t have the sense to approach this thing in some rational way. It’s scary. And it’s an example of why this country (and our world) is such a messed up place (and getting messier by the day.) If you use Photoshop or Paint, then you can “cut” a little piece of one of the squares and “paste” it onto the other and you’ll see that it blends in perfectly (no need to use the “dropped” for those who have a fear of that or think it might be bugged.) Being unable to get beyond the way things APPEAR to you is one of the reasons this world is so f—ed up.

November 13th, 2009They are same colour…. You idiots, if you don’t have photoshop, take paint and try first picture there.
