I think this varies a lot based on the environment...
I've seen :
- Red for external ("hot"), Blue for internal ("cold")
- Red for external ("stop this"), green for internal ("go/trusted")
- Red for internal ("stop this from leaving") and green for external
("go go go to the outside world")
- A combination of the either of the last two with "Yellow" for a
cautionary DMZ area
And then there's the environment I'm in right now, where there are a
LOT of different cable colors for different reasons.
The reality is, from my experience, to find a color combination that
makes sense to you and is intuitive to you and the people who'll be
working with the cables.
Amusing cautionary tale: confirm that you don't have any color-blind
staff, and if you do, make sure they can differentiate all your cable
colors before you set them in stone and deploy them. :-)
cheers,
