Interesting thoughts. I had an observatory in the back yard for 8 years. till I sold the dome. I can't remember the exact colour of the inside walls as I never really looked at them. I think they were an off grey/green, the standard under colour of colorbond sheets. The dome was painted inside with a flat black. When I was in the observatory I was too busy looking through the eyepiece and besides it was too dark to see the walls.
