Bedroom color for ADHD

I vote for a soft blue or green. When we bought our house and were painting before moving in, I was in a tough spot--my girls share a room, and one was hyper and I wanted a calming, quieting color for her, but dd #2 was so extremely quiet and sedate I thought a calm color might send her into a coma ;) I ended up going with very bright and energetic colors, trying to charge up the energy level of #2. That was 3 years ago, and she is much more noisy and lively these days--whether the colors helped or not, I can't say. Big (hyper) sis often remarks she wishes the room was painted the same purplish light blue that my room is--she loves to read and relax in my room, so when we repaint this year, I am going to honor her wish. I'll have to wait and see if #2 goes back to her still and silent self :)
