No. Here is an example of a font available in two variants. In one variant, all those grey swirls are fused to the letters, and it can all be printed in black or one colour ink. http://cdn.myfonts.net/s/aw/original/255/0/131020.png
There is also a second set of fonts included which separates the swirls from the letters, and those can be used in typesetting to get the two-colour effect you see here. That can’t really be done using standard encoding. You’d probably see IIVVOORRYY in the backing store for that word, with every other letter being set in the letter font and the swirl font.
Emoji-style colour fonts use other mechanisms for colour.
