Because colour is not a module, it is a record. Sorry, I assumed that
people would be familiar with Pascal records (similar to C structs) and
it wouldn't need explanation. My bad :-(

The closest example in Python would be:

def class Colour:
    def __init__(self, blue=0, green=0, red=0):
        self.blue = blue
        self.green = green
        self.red = red

which would become something like:

def class Colour:
    def __init__(self, blue=0, green=0, red=0):
        # pseudo-Python code borrowing concept "with" from Pascal
        with self:
            blue = blue
            green = green
            red = red

And now you can see why Python doesn't support this idiom.
