Thorughout Halo Forerunners have used the color blue to accent their gray structures. However, in Halo 4 we see that Orange and Green are also used on occasion. I can assume that Orange is used by the Warrior-Servants, or at least the Ur-Didact, and Blue by the Lifeworkers and/or the Builders. But what about Green? Does each rate have a different color that represents them? If so, what are they?

I believe that was the thinking in HALO 4. Not sure what the Green represents, however! Any answers out there?
