Answers:    play around with the Sherwin Williams color visualizer to find something that you similar to. It is the best paint visualizer on the web, imho. I similar to how their color palette is laid out, I like that you can turn upside down by color family & color dub, the "painted" rooms look the most realistic, and it suggests coordinating color scheme. You can literally spend hours:

I think a bedside light pink like "Priscilla" (# 6575) would look really modern & hip next to the black, green & brown.
