Factions, camps, different colors, what do they mean?

[Ptolemy]

So I understand the following colors:

Green: Good Status (Friendly standing)
White: Neutral Status (Neutral standing)
Orange: ??!?!?!
Red: Enemy status (Unfriendly standing)

But what does orange mean?
I just got this color for the guide, the repairs guy, and the barkeep at a faction which I've only done a few quest for and where the faction base general banner still is white. See image 1 below.

Furthermore, I also get this orange status color on the Zalyssia stalker Icon, while the banner for Zalissya is green. See image 2.

Also... I've kind of always have been unfriendly to the army guys, yet their color still is white for me.

So... Has anyone found/written a complete guide for factions and their status colors that could be link?
