1: You have no idea what their skin color will be, or even how lack of sunlight will weight on it's saturation.
The Quarians are in essence mammals, give or take their young grow in the womb, they have milk glands, they have mammal-based sensory organs. All mammals that do not possess furs utilize melanin pigmentation.
Having little or no access to light, their skin
probably (as I said before, probably, not does) have pale skin.

2: They may or may not have facial tattoos, but that doesn't mean they aren't born with any markings of some kind.
What purpose would those serve? They evolved on a peaceful planet, they had no need for horns or the like. Natural face markings have no benefit, they are not a useful trait in evolution, thus, they probably don't have those.

3: Like said before they can't cut their hair very often(if they even grow hair), and even if they could, they live in envirosuits with climate control, not just a bucket on their head.
They may have chemically treated their hair to not grow much, and you are right at the point they may not even have hair.
Your move.
