If you use Firefox you have to try the ColorZilla extension.

What about a chart for 3 digit compressed color codes used in CSS?

If a CSS code is using a 3 digit compressed, I look to see if there is a repeating pattern in the code and I break the Hex into 3 (usually works) or I take the first 3 (but #fff as a 3 digit doesn't result in white while #000 would result in black -- so a 3 digit code can be tricky)

Here's a good explanation (of Hex) with a color table: http://www.lynda.com/hex.asp#

Does anyone have a chart of a straight 3 digit compressed?

P.S. I often use the color schemer suggested by weisinator above
