Well one of his armors has the same color (The Avenger) it even says that in Wikipedia.,
"Avenger: After defeating Shellshock, you have access to this armor. It is a deep army green. There are more armor plates, and the pieces resemble those of the Master Chief from the Xbox game Halo: Combat Evolved. The shoulder spikes are removed. "
