I beg your pardon? Did you say that you have four piercings, including tongue and cheek? Ugh, yukky, yuk, John!!!
If you felt like dragging yourself to the News page on Narniaweb, you could find out that the Telmarines are being cast as sort of Mediterranean looking, pirates from Mediterranean countries + South Sea Island women having produced reasonably tanned people.... Apparently the casting search for Caspian included non-English countries, but I'd expect the actor to need to be a good English speaker.
This leaves room for the Calormenes to be darker skinned still.
