every primarch is unique in his features and mutations and thus people with the knowledge can tell the legions apart. to quote a previous post form here:

"The skin of the Astartes changes depending on how the Primarch looks: The Salamanders were black even before they re-connected with Vulkan (how this works no one knows) the Space Wolves were pale before they met Russ, the Blood Angels were fair-skinned and blonde before they met Sanguinius, not because they were born that way, but because the superior gene-set of the Gene-Seed overwrote the original gene-structure. Sure, some would look a bit different, a Blood Angel with dark hair, a Space Wolf with tanned skin, it's not much but they're different. What if the 2nd Legions Astartes were like the Salamanders? Or the Night Lords? How do you go "Pfft, they're just a bit mutated from our incredibly pure gene-seed, that's why they don't have any sclera/that's why they have charcoal black skin."

People ask why the only black space marines in the galaxy are the Salamanders? Because Vulkan was black. Sure, you have Jonah Orion, but he's the only other. You can be black, white, asian, hispanic, it doesn't matter, you'll change because your body goes "Oh! This is better genes, let's use these instead!" which is one of the main points of the Gene-Seed. "
