I think I saw a color picker recommendation buried in the how-to file of something but I just wanted to share my FAVE picker with you because it will grab a color from ANYWHERE. So if you see a color scheme on a color wheel or color scheme web site, you can "eyedropper" and then use the RGB value to assign an exact color for text, captions, paper fills or whatever else. It sits on top of all open applications so it works really nicely with SBM.
It's called COLOR COP and you can get it free here:
