The discussion centers around the perplexing nature of optical illusions, particularly focusing on the famous checker shadow illusion where two squares, A and B, appear to be different colors despite being the same. Participants express frustration in reconciling their visual perception with the reality of the colors. Various methods to prove the squares' identical colors are suggested, including printing the image, cutting the squares, and using digital tools like the eyedropper in image editing software. Some users share additional optical illusions, while others debate the effectiveness of different techniques to demonstrate the illusion's trickery. The conversation highlights the cognitive dissonance experienced when confronted with visual discrepancies and the fascination with how the brain interprets color and light.

LOL! Dave, you have funny looking square fingers. :smile:

Dex, it's the same optical illusion tricking you into seeing shades of gray in the overlaid box. Do it yourself (that's what I did). I just used the eyedropper tool to select the color in A, drew in a rectangle connecting the two squares, and filled it with the color in A. Lo and behold, it really is the same as the color in B, but even with the rectangle there, my eyes still wanted to interpret the squares as different colors because of the shadowing effect. Really nifty, huh?

Printing it off and physically cutting it and combinting the two squares is the best proof for me...

But while you're using the eyedropper, why don't you just look at the RGB value for square A and square B?
