Why are most players content with putting on generic glamour?

My miqo'te has a dark brown skin and it's like super-rare. I don't meet other miqo'te using this color.

I very rarely see dark brown skin at all in-game (JP server) other than the occasional male Roegadyn. Your Miqo'te is really cute. I can't stop watching the GIF :/
