""" Convert values between RGB hex codes and xterm-256 color codes.

|
||||
Nice long listing of all 256 colors and their codes. Useful for
|
||||
developing console color themes, or even script output schemes.

I'm not sure where this script was inspired from. I think I must have
|

written it from scratch, though it's been several years now.
