Color Optical Illusion
April 1, 2007 · Filed Under Optical Illusion and Magic
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

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.
