Quick tutorial

Source this script:

. ./src/color.class.sh

and execute color.help or read the docs :-)

Example 1

Set a color. Every following command uses that color until you set a new one or reset it.

color.fg "blue"
ls -l
color.reset

Example 2

Echo a single message in green and reset the color afterwards.

color.echo "green" "OK. I guess you got it."

Colors

To set a color you can use ansi code, color names (see table below) or rgb heccodes (like css color codes).
