What color are 'The Borg' from Star Trek ?

[Yoda from San Diego]

Since the Bork are a collective they must be either blue, green or turquoise, right ? Which one is it ? Blue ?

[RichardY]

Collective unconscious. Orange. 

Individually conscious ego, but they aren't individuals, they're slaved to a greater collective.

"The Borg are the ultimate user. They're unlike any threat your Federation has ever faced. They're not interested in political conquest, wealth, or power as you know it. They're simply interested in your ship, its technology."

[RichardY]

"They've identified it as something they can consume."
