Trade Lines

I figure this will be an easy one for anyone that knows the answer, and while I've wondered what the significance is for awhile, I've never bothered to try and figure it out, till now anyway.

I'm staring at trade node lines in a co-op game today, and it occurred to me, while I patiently waiting for my partner in crime to make his move, I've no idea what the different colors mean for the trade lines.

I'm pretty sure I've seen white, yellow, red and green. And I've got a fair idea that red means another clan you're at war with is cutting you off on that line, but I've no idea what white or yellow is, and of course suspect that green means everything is all good.

Anyone out there care to enlighten me here, and btw, if I missed some colors, throw those in too! :yes:

If I remember correctly the only colours are Yellow, White and Red. Green might be a transition.

Yellow- Includes your trade lane.
White- Neutral clan trade lanes.
Red- Hostile Clan Trade lanes.

Colour priority is Yellow, Red, White.

Very cool, thx man.
