There isn't solid text evidence for any of those things, although lots of people have pet theories. (Vorbarra livery is mentioned from time to time, I think Gregor even wears it once or twice, but the colors are never actually named--it's just referred to as Vorbarra livery, or the Vorbarra colors.)

From what I've read, Lois's standard operating procedure is to leave details like that as unspecified as possible unless they become story-necessary, so that she has maximum maneuvering room later on. Also she hates making up character names. :)
