Color.

How to use.

Most of the time you want to use it with echo. To make echo respect colors, you need to use -e flag like that:

export color_default="\033[0m"
export color_red="\033[0;31m"
echo -e "${color_red}hello world!${color_default}" # will print "hello world!" in red.

Don't forget to use color_default at the end, or your whole terminal will be red.
