A $5 "Oops" can of paint at the hardware store. I never thought I would paint a room light blue, but it completely energized the room and gave it a clean, fresh feel. The room is pretty small, so I used white to maintain the crispy vibe, and the grey was added to match the daybed I love.
Colors used in my room:
Valspar Rain Dance, Sherwin-Williams Site White
Tips for using color successfully:
Match your pets! I pretty much do this consciously or subconsciously with furniture colors especially and, as you see, my snuggly kitty is mostly grey and white. If you don't have pets, think of something you eat or drink all the time and match the stains you make. (I kid, sort of - see how that floor is chocolate color?)
