Interesting, but illusion 3 is not what it says. If you pull the mask down so it just makes the top of the 2 centres appear you can clearly see the difference between the grey/purple on the left, and yellow on the right.
Hmmmm, I think they are the same...........I did a screen capture and cut and paste both centres and move them across next to the other.....and they look identical.
Now you have messed my head up Brian 2 and 3 do look the same color !!! but to me number 1 is like black vs white
Think Im off for a sit down in a darkened room
