If you are unsure, it is often a good idea to start with something that professionals recommend. Most home improvement stores and paint vendors offer a selection of palettes that work together.

Here's how to do it:  Saturated colors can have a strong effect on your emotional state. A bright red room might make you feel nervous, and a dark grey one might give you the blues.
