Why would Kat's visor color be listed as "not in armory," while Emile's, Jun's, and Jorge's colors are Bronze.
I think gold is close enough, but then couldn't Kat's visor color be listed as Silver?
It looks close enough to Silver.
EDIT: If you look at the desciption of her helmet in the armory, it says it's an upgraded version of the ODST helmets, which have Silver visors (At least in Halo ODST while in sunlight.)
