Here is the simplest and readable solution. With bashj (https://sourceforge.net/projects/bashj/), you would simply choose one of these lines:

#!/usr/bin/bash

W="Hello world!"
echo $W

R=130
G=60
B=190

echo u.colored($R,$G,$B,$W)

echo u.colored(255,127,0,$W)
echo u.red($W)
echo u.bold($W)
echo u.italic($W)

Y=u.yellow($W)
echo $Y
echo u.bold($Y)

256x256x256 colors are available if you have the color support in your terminal application.
