What breed?
Out of the cream x broken black, you'll probably get chestnuts and broken chestnut, maybe with some chances at other colors like black, broken black, opal, broken opal, orange, broken orange, etc, depending on what the two carry (if the cream carries self, and if the broken black carries non-extension or dilute)
Out of the frosty x cream, you'll probably get oranges, maybe some cream, frosties, blue frosties, or even tort if the two carry the right genes.
