Hex Color Picker from waffle software (the same group that did Google+Growl, a nifty little program I use every day) adds another tab to the Mac OS X Color Picker for dealing with colors in terms of hex values, a system more familiar to programmers and web designers than a box of crayons.
It works really well and it’s free. Try it.
