Oh yeah, and if you don't like the colors you're getting... bad luck I guess! ;) Just change the offsets in cut to something else (up until 32).
The colortrans.py script, slightly modified version of https://gist.github.com/MicahElliott/719710:
#! /usr/bin/env python
""" 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.
Resources:
* http://en.wikipedia.org/wiki/8-bit_color
* http://en.wikipedia.org/wiki/ANSI_escape_code
* /usr/share/X11/rgb.txt
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.
