    ### Bash colors and formatting

    # To set the formatting/color, use the following:
    # - escape character (\e, \033, \x1B)
    # - open square bracket
    # - attributes (semicolon-separated)
    # - the letter m
    #
    # \033[<attribute>;...m

    ### FORMATTING (+20 resets the value)
    # 0 Reset all formatting
    # 1 Bold
    # 2 Dimmed foreground
    # 4 Underscore
    # 5 Blink
    # 7 Invert fg/bg colors
    # 8 Hide text

    ### COLORS
    # Dark | Bright
    # Foreground: +30 | +90
    # Background: +40 | +100
    #
    # 0 Black | Gray
    # 1 Red
    # 2 Green
    # 3 Yellow
    # 4 Blue
    # 5 Purple
    # 6 Cyan
    # 7 Gray | White
    # 9 Default | Not available



    # This file echoes a bunch of color codes to the
    # terminal to demonstrate what's available. Each
    # line is the color code of one forground color,
    # out of 17 (default + 16 escapes), followed by a
    # test use of that color on all nine background
    # colors (default + 8 escapes).
