White yurt cover, why so popular?

I have the light tan roof, and i did it because it seemed logical. With good

insulation

in the ceiling I don't think it will make much difference. If there are any trees near your location, a light colored roof will take on tree sap/goo/crap and become streaked with stains. It adds character. If you get a darker roof, the stains will still be there but you won't be able to see them. And remember, it is much better to beg someones pardon than to get permission. Good luck!
