I am going to addendum what I just wrote. Cool can be anything from the sky can be anything from the bright white, to vibrant fushia, and even some reds (usually described at true red). Warm can be anything from parchment white to yellow green, and some of the warmer reds (burgundy/brownish reds, red tinged with copper type reds).
Another great website (I know it sounds strange but they actaully make there business with color so it does make sort of sense) is
http://www.crayola.com. They have a section called color corner which is great for general information.
