Not confirmed. He could just be red.
WikiThe part about his appearance on Backwash should be ignored, in my opinion. Multiplayer maps aren't exactly canonical.
Plus it says on the Backwash page:
It is actually stated by the developers of Halo 2 that Backwash was originally set on Alpha Halo and based directly on 343 Guilty Spark. It is also stated that they originally had 343 Guilty Spark floating around but decided to change him to 2401 Penitent Tangent because the blue glow of 343 Guilty Spark's eye could too easily be mistaken for a Plasma Grenade flying through the air.
So really, it's a non-argument. I still stand by the combat-mode theory, even more so because blue is a core theme of Forerunner design and that Mendicant Bias is also blue.
If anyone was going to bring up 686 Ebullient Prism, I'd hasten to add that artistic license in comics can and probably should be ignored rather heavily (plus he seemed rather rampant during the comic).
But meanwhile, your best bet is Coup d'Bungie which you can find hidden somewhere in this thread.
