Using the colored gem

    require 'colored'

    a = []

    a << " test ".red
    a << " test ".red_on_blue
    a << " test ".on_red
    a << " test ".on_green
    a << " test ".black_on_white
    a << " test ".on_yellow
    a << " test ".on_orange
    a << " test ".on_purple
    a << " test ".on_brown


    a << " test ".red.underline
    a << " test ".bold.blue
    a << " test ".red_on_yellow

    puts a.join("\n")
