This may not count for much...but....as a male Ciel....I noticed that most girls tend to majorly over do the whole makeup thing. It's difficult to pull off a young look when there's layers of eyeliner/eyeshadow ^^;
But...besides that....I'd guess you match the palette to whatever version you're doing. I'd also guess that you'd just do the basic cosplay makeup; foundation and whatever else you would usually wear.
