OS X Hex Value Color-Picker Plug-In

Recently I was throwing around an idea about making a plug-in for the standard color-picker panel for OS X. All I really wanted it to do was give me the hex value of the selected color. I did a fair amount of research and eventually found that someone had already done it. I’ve never seen that advertised, or shown anywhere; but so far I’ve found the plug-in proves useful. Now if only the author would make the source available so a good example of how to make a color-picker plug-in would be available…
