You're confusing colors with attributes. I recently stumbled across that
one, too :)

This will do the trick:

# define color 1 as black on blue
curses.init_pair(1, curses.COLOR_BLACK, curses.COLOR_BLUE)
stdscr.bkgd(' ', curses.color_pair(1))

If you're getting this error:
  File "clock.py", line 6, in mymain
      curses.init_pair(1, curses.COLOR_BLACK, curses.COLOR_BLUE)
      _curses.error: must call start_color() first

your TERM setting doesn't allow colors. You can then use something like
TERM=xterm-color instead.

Btw. there's a curses howto on http://py-howto.sf.net/ in case you
didn't know.
