There are no 'structures', as such in Python (not in the C sense). A 
color class could be defined like this..

class Color(object):
     def __init__(self, r, g, b, a):
         self.r= r
         self.g= g
         self.b= b
         self.a= a

You can use instances of Color as a default parameter, but because 
defaults are evaluated once (at import time), it is usualy better to use 
None as the default, and act accordingly. eg.

def renderABezierPath(self, path, closePath=True, outlineColor=None, 
fillColor=None):
	outlineColor = outlineColor or Color(1.0, 1.0, 1.0, 1.0)
	fillColor = fillColor or Color(0.0, 0.0, 0.0, 0.25)
