I got a nice room in my basement (thanks to my wife), that I can convert in a small studio. The ceiling is actually white (4x8 styrofoam panels). My problem is the walls are actually beige and a weird color between orange and red. Since I would like to use them to bounce some light, I want to repaint it. Should I use the purest white I can find? Would you go glossy or flat? Do you have any other ideas or experiences?
