Commandline color picker and palette builder
Overview
tcolors is a commandline application for creating palettes of one or more colors in HSV space. Created palettes and their colors may be output in several different formats for import and use into other programs.

The term output option provides a series of named functions for easy importing and terminal use
# tcolors -p -o term
_colorbg() { echo -ne "\033[38;2;020;020;020m$@\033[0;00m"; }
_color0() { echo -ne "\033[38;2;255;119;051m$@\033[0;00m"; }
