I'm not arguing for PIXEL_FORMAT because both the shift and the mask is 
well defined.  One way to explain Color would be to say that the shift 
is 0 and the mask is 0xffff; that'd be clear and unambiguous no matter 
what the context.

The reason I think this is not clear, is that there are so many 
different graphics specs all over the technology spectrum, and some of 
them only use the lower bits, based on what the resolution is -- for a 
5:6:5 format, they'd use the lower 5 bits of red and blue, and the lower 
6 bits of green. You can't assume that just because you think the way it 
current is defined is "right," (and I would agree) there won't be some 
other context within which a loose definition wouldn't be confusing.

Sincerely,
