As I’ve said in an earlier post, the basic principles of color are hue, value, intensity and temperature. When you combine these four areas in the right way you’re going to be on the way to some great color decisions.
One of the four principles is temperature – You’ll hear people talk about colors as warm or cool. You can set the mood of the room if you know how to maintain a balance of temperatures. Warm colors would be colors like red and yellow. Blue and green are called cool colors, and then there are neutral temperatures such as beige. Not only will the proper temperature set the mood of a room, it can also modify and define the perceptions of a room or space.
