I think first and foremost, paint it a color that makes you feel happy and creative! Color has the ability to alter our emotions, so go with what makes you feel the best. Warm colors, like orange, red, yellow are lively colors. Cool colors like blue, green and purple are a bit more soothing and calming. Neutrals are just that, pretty neutral, but a nice background in many rooms to let the accessories carry the color and style in the room.
Just my two cents worth! :D :D
