Purple?!?
It is blue and black. That heresy alone would be reason enough to assimilate you, so that you are able to correctly identify colors.
And what about UF armor being shinier than ours?!?
Let me think about that one for a second... UF armor usually looks black, rusted, generally speaking: used and old (return from your grave and try to look shiny after several decades in wet earth...
). Then, thinking about Black Ice swarms standing in the glazing sun of Mistraspera, blinking with their highly polished stainless steel looking (its really essence) armors like your holiest wanna-be-knights would love to look like....it is simply grotesque to say that our "kits" as you call it, look less shiny as those of our undead allies. 
To sum it up: again you have proven our point, settler. You have once again shown how far away from the perfection of the essence you are. That what we strive to achieve and where we are on our way is more advanced and closer to perfection than you will ever be in your lifetime. Not even being able to discern between simple colors and who is wearing the real steel.
I pity you for your ignorance of the real world, but maybe that is the way it has to be for you to survive and do whatever you are doing in your blindness. But alas, in the end there will be peace in the unity of the ESSENCE!
P.S. Thanks for the flowers about being the nicest NPCs!
Cookies are for the assimilated! Additionally sweetening the joy of eternal perfection! Join and.... hum, got distracted... what I wanted to say:
