The books was notorious for leaving out details on how people were dressed and what things looked like (maybe an offhanded comment on Paul having black hair like his fathers), but I do remember they said that house Atreides uniforms/clothes were black and their symbol was a red hawk. Looks like they got the black down. Plus some battle armor is a cool idea considering melee combat is a thing. I am also really digging these stillsuits.
I think I recall something about the Atreides being descended from Alexander the Great, and having 'olive skin'? Not sure that's in F. Herbert's books, though, could be in the sequels that his son wrote with KJA (Yes, I read some of them - sometimes I suffer insomnia and will read anything that happens to stray onto my Kindle. And yes, they're
bad ...).
As to looks: The Dune Universe is set 10.000 years into our future. There's genetic
studies of La Brana 1, a hunter-gatherer who lived in Spain 7000 years ago - blue-eyed, closest genetic relation apparently modern-day Scandinavians and ... dark-skinned -
"African variants for the pigmentation genes" (also lactose-intolerant).
Or meet 'Cheddar Man', the 'first modern Briton':
Who knows what people in 10.000 years will look like?
