Yes If you breed a Black orp to a Buff orp, the chicks will technically be pure Orpingtons, just mutty colored.
Here is some possible colors on post 5 https://www.backyardchickens.com/forum/viewtopic.php?id=320183

If your Comets are the typical comets that are red with white tails, then breeding a black roo to them should give white birds probably with black spots ( its not splash though, its from the Dominant white in the comet hens, unless your black roo may be gold based then you may get some more gold colored chicks.
