IF I have light blue carpet and three different shades of blue paint on my walls, a blue comforter and a blue guitar and a blue nightable, in addition to a white desk, a white sheet over a chair and a grey stereo, it can aid in my depression, correct? don't get me wrong, at first it's very relaxing but now I find it's really making my pretty upset.
I believe that combination gets you relaxed. It could also get you into some sort of trance and awaken some intallectual and artistic abilities (unless there is lots of light through the windows). If your lookeing for colors to cheer you up, try something like yellow, orange, or lime.
I don't think blue is a very good colour if you are feeling depressed, bright or warm colours, and adding some pictures and posters that you really love, might make it more cheerful. I hope your feeling better soon
