What are the pictures/colors you see when you close your eyes?
I see reddish-orange, because the light is coming through them.
Black and white random stuff.
a dark orange color
White spots .
The short/term colours are caused by your receptors trying to compensate for the average stimulations in the past. Long term colours are, as far as I know, your nervous system's background noise and your brain correlating this noise.
I see tiny white Dots on pitch black background, and the dots are all in alignment And vibrating.this is in a totally dark room.
