Different Shades of Skin Color?

[Hannibal Khan the Great]

Yep, especially Pahlava, Sauros, and Saka (well all Iranians) could have a wide variety of skin. Remember, in EB1 some of pahlava's units were dark while others had pretty light skin, even had blonde hair. Saka and possibly Baktria could even have some Chinese or Turkic faces representing some living in their lands.
