Still, the Vitamin D was a factor for the maintenance of that darkness. The Elves, who are pale to begin with, have no swarth to maintain, so they'd keep their pallor. I eat a lot of fish and I'm still not very dark because I'm a Cajun who doesn't spend a lot of time outside, for example. I think that's the point Raineh's making.

As for snow, yeah, the high albedo can do that, but I think cave-dwelling largely negates it.

I got ninjaed don't yell at me
