Yup, and those are all huge things that are kept unique. You can very firmly be an iconic Blood Elf and the Alliance players do not get that at all!
Conversely, you can be an iconic Void Elf and Horde players do not get that at all!!
What's shared are the iconic 'High Elf' look. Which is pretty much human skin tones + blue eyes.
An argument for hair color can be made, but there's at least one regular hair color coming to void elves (black) which fits with the normal hair colors High Elves often have.
