blackening walls?

My observatory is just about ready for the scope to move in; I was wondering if you all think it would be worth the effort to paint my walls black. I don't know what any downside would be, maybe heat loss issues? Any other ideas?

Yeeessssss !! Paint your inside walls.

That's worth the pain. For my observatory, i've used Corostop black matt paint. That's create a REAL dark environnement inside the observatory. For visual use, it's amazing, the black matt color cut the light reflection inside.

I used a dark Navy blue instead of black...sort of matches the inside of the Home Dome. Of course, under the red lights, it appears black.
