Colors

A line with a new line and colored text can be made with

echo -e "\e[32mGreen text on the default background\e[0m"
echo -e "\n\033[01;44;37mWhite bold text on a blue background\033[00m"
echo -e '\n\e[32;40m'"\e[1mGreen bold text on a black background color\e[0m"
for i in {0..255}; do printf "\x1b[38;5;${i}mcolour${i}\x1b[0m\n"; done

Foreground colors
For background colors replace the leading 3 with a 4
