Display All The Terminal Colors

The following snippet of bash scripting will print out a nicely formatted collection of all the terminal colors.

for x in {0..8}; do 
    for i in {30..37}; do 
        for a in {40..47}; do 
            echo -ne "\e[$x;$i;$a""m\\\e[$x;$i;$a""m\e[0;37;40m "
        done
        echo
    done
done
echo ""

This is a great way to figure out the escape codes you need for coloring and styling text in a bash script.
