I don't know why the focus on this individuals skin color.
Because potato there is not enough data to focus on something else. Of course we always can turn "drill sergeant mode" on, sort of "your hairs not cut to regulations", "take that hat off, you're inside", and "had you polished your boots and brass, and ironed your clothes?"
Even though Brad has suggested they have blue skinned Altarians, it could very well be a light colored Altarian and the blue colored panels are making the skin and enviroment blue.
As long as we won't have green and red skinned Altarians simultaneously with blue skinned ones, or had to pick up one of tones, I'm fine with that.
Though I can't get those two points out of my head anyway.
