Well, perfect pitch doesn't necessarily include being able to pick out chords so well, since they are more complex than a single note. However, if you played any chord, I could probably tell you if it was major, minor, diminished, or augmented. I might mix diminished and augmented once in a while, maybe, but honestly, I don't have anything close to perfect pitch, and telling between major and minor is pretty damn easy.
Also, for some reason, I'm attuned to Gs. If there's any note or chord I'm most likely to be able to name by ear, it's a G, for some strange reason.
