Your retina and pupil is being squeezed so much that it is contracting all the Цвета in the area and transfers it into your eye while Ты are rubbing them. This is what I found while searching it.

I was told something along that line when I got this big floater - when I closed или moved my eye suddenly, I would get this burst of colours. The doctor explained it as being caused by the shrinking of the eyeball. The same effect could also happen if Ты have something seriously wrong with the eye.
