Yes! In fact, my bedroom had a red wall, and only recently painted it blue. I must say, it's much more soothing, calming and relaxing to lie down on a blue-colored room. I recommend it to everybody, especially people who are often stressed or suffer with anxiety. If you're planning on having yours painted, I recomment getting an estimate from https://www.homeyou.com/directory/painting . They're the ones who painted my bedroom, and I couldn't be happier with the result.
