With PEP343 (I guess in Python 2.5), you will be able to do something like:
with renamed(colour) as c:
     c.red = 0; c.blue = 255; c.green = 0

I think however it is bad.  Better solutions to me would be:

colour.setRgb(0, 255, 0)

or

c = myVeryLongNameColour
c.red = 0; c.blue = 255; c.green = 0
