We've been redoing our bedroom, and just for fun we did a little research on how to Feng Shui your sleeping quarters. We found that the most soothing colors for a bedroom are skin tones: pinks, taupes, and browns. (Although the best colors for you depend on what you like and how you respond to different hues.)
We don't know how much truth there is to be found in our quick Internet search, but it does make sense that skin tones would promote good sleep and, well, good sex.
Plus, we recently painted the walls a light chocolate color and bought new pink sheets for the bed, so we're happy to hear we're on the right track.
