I know of lots of ways to do this...

... but they are all platform dependent; not just Windows vs Unix, but 
PIL vs wxWin vs whatever.

def search_screen(desired_color):
   root = my_gui.root_window()
   width, height = root.get_size()
   for x in xrange(0, width):
     for y in xrange(0, height):
       if root.get_pixel(x,y) == desired_color:
         return x,y
   return -1, -1

Modify the above using the appropriate values for 'my_gui' and its 
methods, 'root_window', 'get_size' and 'get_pixel'.

You're welcome.
