The official description of the Trojans says that they are made from Knights who got lost in the Clockworks and never returned.

However, whereas player Knights come in a variety of colors the Trojans only come in... 3 colorschemes, and they're Tiered versions of the Trojan so that's 1 colorscheme per Tier.

I think that the Trojans in Tier 1 and Tier 2 should be changed aesthetically to reflect the fact that they are corrupted Knights. The Tier 3 Knightmares can remain the same (presumably since the closer they are to the Core the stronger and more drastic the "corruption" that made them into Trojans is, thus making their appearance converge to the same standard).

I propose that they should either come in the color schemes that accessories are available in (minus Divine and Volcanic of course), or should have the same colors as Players.

I would also like the emblems on the shields to be randomized as well. Perhaps they can match the Gate symbols...

Or perhaps all the levels that can have Trojans spawn in them can get a Trojan coloration that matches the ambience of the surroundings (suggesting a connect between the Knight and the place they went missing before becoming a Trojan) whilst maintaining the appropriate physical/attacking characteristics that a Trojan should have at that depth (meaning the fighting's the same).
