What color is best to paint a room with hardwood floors to enhance productiivity?
There are plenty of theories on these sorts of things, but very little hard science. I would say that the best color is one that makes you comfortable and keeps the room fairly bright (but not uncomfortably so). When there is more light, you see better, there is less eye strain, etc. and all of that should make you more productive. It also saves energy since lighter paint will reflect more light and require less output from your lamps.
