I used to get this effect by shutting my eyes really really tightly when I was about seven. I did it when I couldn’t sleep. After I’d done it, my eyes always felt tired and I guess I used to drift off.

I told my friend about this and he said that he could see brilliant reds and yellows by shutting his eyes and placing his thumbs on his eyelids and applying pressure.

I assume that the “brilliant” colours are caused by the increased pressure within the eye causing problems for the optic nerve. Not a good idea.

I saw him two years ago. I’m not sure if he saw me; his glasses looked like they came from Hubble. Funny that.
