Are your humans “different”?

In a fantasy world with elves, dragons, and demons and such, when you add humans to your world, are they exactly the same as your humans here in real life? While it makes sense to do just that, I feel like it makes equally enough sense to give them alternative physical quirks or attributes. In my Sigilist world, humans are similar to irl humans, but can be born with brilliantly colored hair; not just brown, black, blond, orange, and variations of those, but also silver, maroon, lime green, and electric blue. Does your worlds’ humans have alternate qualities to them while still being “human”? Edit: Humans in my Sigilist world have the same color eyes as their hair (i.e. Silver hair=silver eyes and so on)
