Do they provide the appearance of having that dark red color or is it straight black?
If not, then a very thin layer of Tamiya clear red tint may be in order.
They are painted with the tint.
Accurracies and all that put aside, the sheer production quality on this figure is amazing, I'd say this thing could rival a Premium Format in the overall look, the finish on the helmet is just amazing, the detailing, the quality of everything is just really well made. Definitely the best made Sideshow figure I own.
