What strikes me is that the likelihood of someone wanting to colour the
alif portion of a lam-alif ligature is comparable to someone wanting to
colour the dot of an i or the cross-bar of a t. It's not exactly an
everyday need, I think. The fact that it is easy to provide a markup
representation of the former is coincidental.
