Description
This is an optical illusion that I came across in a book recently and wanted to try to reproduce in C4D. Look closely at squares A and B. They're different shades, right? WRONG! Squares A and B are exactly the same colour and shade. You can verify this by covering all the other squares with pieces of paper until just A and B are showing, or load it into a paint package and check it with the "dropper".
I know it's hard to believe, but it's an amazing illusion and it works...TRY IT!

Well if you're stoned, my friend, I must be too, 'cos my brain's TOTALLY confused over this one. How can the two squares be the same colour? Even though I made the darned thing myself I STILL can't figure it out...pah!

I got this from a friend a few weeks ago. I posted it over the copier where every-one could see it. The next day we're all huddled around the monitor while I checked the numbers in photoshop. The VP of marketing is like "no fucking way!" we all cracked up. Ah the joys of working in advertising

whohooo.. if you think your "dropper" is wrong -- which is NOT -- try this. select and copy area A and pste it into a new document. then do the same for area B and compare!!!! how cool is that

Yup, it's weird. Try looking at www.cs.stir.ac.uk/~dec/optical.jpg for the original. I sent it to my lecturer and it made it in to the lecture notes. Interestingly, the explanation is do do with our perception of colour. Our brain tries to correct the colour because it is in shadow. This is do do with 'colour consistency'. Any object you look at in any light condition seems the same to you, for example your jumper will always look 'that' shade of blue. I'm sure the checkered pattern dosen't help either! check out http://www.cs.stir.ac.uk/courses/31N5/web2002/handouts/12-co_upd1.pdf Sorry for massive exlanation but this thing scares the hell out of me!

i have also seen this one before, check this flash animation http://www-bcs.mit.edu/gaz/gaz-teaching/flash/koffka-movie.swf you can see the color change right before your eyes, very cool!

Just dropped by the C4D-gallery. Lots of inspiring stuff - this one has a twist, cool demonstration. I just can't believe my eyes ;o) This demonstrates that you never see "the world" as it is, but only your interpretation of it, and that may or may NOT be right...

Thank you for messing my mind up even more than it already was :) FYI Did you all see my illusion also :) http://www.renderosity.com/viewed.ez?galleryid=224717

well, I tried the eye dropper theory and in RGB values there is a difference in each color by a value of 4. (58 versus 62) I don't mean to sour your model, cause the theory behind it still is really cool! good stuff!
EugeneTooms
There is probably a tiny difference in shades at the edges of each square, due to the way it renders...but come on, a difference in RGB of four is just nitpicking!

The differences come maybe from the jpeg-compression.

Magicians harness the power of perception, manipulating how the mind interprets what the eyes see. Through intricate techniques and precise timing, they create illusions that challenge reality, leaving spectators in awe. learning magic involves mastering the art of deception, using optical illusions to captivate and amaze audiences. Understanding optical illusions is fundamental to this craft, enabling magicians to craft mesmerizing tricks that defy logic and spark wonder, making magic an enchanting blend of skill and illusion.
