The way that terminals (and emulators) handle colour is fundamentally
different from the DOS/Windows console. If you want something which will
work on both, you will have write separate implementations for terminals
and the DOS/Windows console.

For terminals, you can use the "curses" package, e.g.:

import curses

curses.setupterm()
setaf = curses.tigetstr('setaf')
setab = curses.tigetstr('setab')

def foreground(num):
    if setaf:
        sys.stdout.write(curses.tparm(setaf, num))

def background(num):
    if setab:
        sys.stdout.write(curses.tparm(setab, num))

For the Windows console, you'll need to use ctypes to interface to the
SetConsoleTextAttribute() function from Kernel32.dll.
