Except in the case where all vertices have the same colour, so the user only does the conversion once and Allegro would do it mutiple times anyway because it doesn't know it only needs to do it once.
Still, I'd like to see how much of an overhead that really is (first of all), and if it's actually bad, hide that information in the ALLEGRO_COLOUR struct instead.
So I agree that, if we can, we should avoid this.
