Think about it: why does someone want to colour part of a ligature
differently than the remainder of the ligature? Probably because they
are discussing something to do with the letterform itself. There's just
as much likelihood, I think, of someone talking about the cross-bar of a

have a bit of contradiction. You say that MS *should definitely*
implement this, and the reason you give is because most Web browsing
relies on our rendering engine. But using that logic one could also say
that MS should definitely implement any esoteric feature someone might
imagine because most Web browsing relies on our rendering engine.
Obviously, the business need must also be a factor, and you've stated
that there's not that great a need for this.
When someone needs to use colour to highlight portions of a letterform,
they can always use graphics tools. Not to say that MS or other vendors
shouldn't consider the kinds of features you're suggesting, but I can't
see justification for a "should definitely implement" prioritization.

I think this would be up to an application to implement, not something
like our Uniscribe component or a TextOut API.
