i wonder why the brain decides to do these things???
i told myself that i knew it was pink dots flashing while lookin at the cross but they still disappeared!!
cool..

Cool. I can't get the pink to disappear, just see pink dots with a light green dripping effect of the pink dots. If I follow the dot it doesn't look green, looks grey.

The reason why you get the green dot is because you are subconsciencely doing a colour subtraction from the grey background and the pink.

The reason why the dots eventually disappear is because the green + pink addition gets you to the grey background colour.

You can do some wicked things with colour perception and interpretation. This is a really good one too.

I also have red green colour blindness.
