For future reference, look in the source code. Sometimes, it's very obvious (e.g. a string that says "background: purple"), while other times, you should be looking for hexadecimals or coordinates (stuff which looks like "#FF1234" or "rgb (10, 20, 30)").

To figure out what hex or RGB colours are, try searching "colour picker" with either one, or ColorPicker.com should do the trick for most of what you want.
