That's interesting. I also noticed that if you focused on the cross in the middle while the dots remained pink then shifted to the outside that you can see a circle of green dots!

Visual preception is based on many layers of visual augmentation. That is, what your brain sees, is about how it combines all the inputs it gets. And it's good at filling in the blanks.
There are many classic studies on visual perception, where you can superimpose slides of two very specific colors and the brain will perceive one not in the mix. Scientific American did a landmark article on this back in the 70's.
Don't get me started! I'll post electron micrographs of the retina. And that will put even the insomniacs to sleep! LOL!
