Yes, an integer is required, be it decimal or hex. A little "lambda" may be of help to create it rather than calculate it by hand. E.g:

Code:
RGB=lambda red, green, blue: (((red*256)+green)*256)+blue draw_filled_polygon([(0,0),(160,120),(0,240)],RGB(120,120,120))

gets you a grey triangle

I'm a Python beginner. Can you tell me why use lambda over the following? What's the advantage?

Code:
def RGB(red,green,blue):   return (((red*256)+green)*256)+blue
