The brain minimizes its sensitivity to a color when this color is present for a long time. That's why you see everything bluey after you lay down on the beach with the Sun over you for a while because the redish color from skin in the eye lids, makes your brain less sensitive to red.
The screen white color is made out of various colors. When you become less sensitive to one of them you'll see the others more.
I get it but I can't explain it.
our brains are awesome!
you can look anywhere in the picture not just the dot :/
I did this for about 200 times...
There's just no way!
You see it but as soon as you move ur eyes it's gone!
