That's right. In short, a CG equivalent to -[NSColor colorUsingColorspace:] is what I need - I just need to ensure that colours that could originate as grays for example, end up as RGBA colours, since I'm doing work directly on the four components. Converting gray is easy enough actually, if I have to do that myself, but it would be nice if there were a funciton that would work across all possible colorspaces.

I thought Id' seen a CG function for this in the past, but I can't remember where I saw it and I may be mistaken.
