This might interest some of the Terrain guys...
This is great little color picker tool that lets grab colors and displays and allows you to copy the Long, HEX and RGB formats of the color you have chosen. It has a pick from screen so you can grab a color from anywhere or any other non modal application
You can also type in Long HEX and RGB if you want and it will translate it to the other formats for you...has a fly out pallet
I have been using this for map making and graphics for years now...
There is no installation...no dependencies and has the foot print of baby when running
