2. I always think about how the room will be used, and then apply a little color psychology. Warm colors, bright colors for more energy (kitchen, living room, etc) and cooler, more subdued colors for relaxation (bedroom, bathroom, etc). 2 good color resources: 1. A good resources for colors and color combinations are pieces of art. Most artists tend to have a great color sense and they combine the colors in interesting ways. 2. I like to collect paint swatches from the paint store. Then I mix them up, turn them color side down and randomly choose a few. Sometimes you end up with really interesting color combinations!
