What is the point of choosing the color of your armor?

Seriously, can any of you actually make out what color your opponents armor really is? I don’t. They are all glowing bright yellow for me right now until I decide to make them all glow a different color. Between the outline and how insanely bright the shields are, I couldn’t tell you what color my enemies are. One thing that is for certain, any money spent on colors is a complete and total waste unless you’re some narcissist experiences great enjoyment admiring “how cool you look” in that opening scene before the match begins.
