In the second one, I'd say it's somewhere between "T" and "S". In general, I don't know how it is with Nebka, but in real life, "T" doesn't have dark or light skin; it's just gray, with little to no warm undertones.
I like Heroist's picture. The woman looks a bit generic, with her high heels, and... Heroist, doesn't she have a scar?
