No need for 'em :-) Here's a lil function I cooked up:

(colorize("red", "Test") prints Test in red, colorize(("red", "yellow"),"Test")
uses yellow background).

enable_color = 1
if sys.environ["TERM"] == "xterm":
 xterm = 1
def colorize(color, text):
    """Return colorized text"""
    col_dict = {
        "black"     :   "30m",
        "red"       :   "31m",
        "green"     :   "32m",
        "brown"     :   "33m",
        "blue"      :   "34m",
        "purple"    :   "35m",
        "cyan"      :   "36m",
        "lgray"     :   "37m",

        "gray"      :   "1;30m",
        "lred"      :   "1;31m",
        "lgreen"    :   "1;32m",
        "yellow"    :   "1;33m",
        "lblue"     :   "1;34m",
        "pink"      :   "1;35m",
        "lcyan"     :   "1;36m",
        "white"     :   "1;37m",
    }
    bg = "0m"
    if type(color) == type(""):
        # In xterm, brown comes out as yellow..
        if xterm and color == "yellow": color = "brown"
        fg = col_dict[color]
    elif type(color) == type(()):
        f, b = color[0], color[1]
        if f == "yellow" and xterm: f = "brown"
        if b == "yellow": b = "brown"
        fg = col_dict[f]
        try: bg = col_dict[b].replace('3', '4', 1)
        except KeyError: pass
    if enable_color:
        return "\033[%s\033[%s%s\033[0m" % (bg, fg, text)
    else:
        return text
