Sakritt being blue has really never bothered me in the least - humans come in at least five basic colors and all the weird blends inbetween, so why wouldn't other species too? If this is the only blue Dom we've ever seen, well... how often do we see Indian characters? And that's from our PoV, where humans make up the whole background and setting.
The SP uniforms are harder to make sense of, though. I'm tempted to just assume they're an easter egg and call it a day.
