That's because purple eyes are a thing. Sure they don't have the no hair below the neck or no period perks but it is real. It affects ( effects ? ) people who have albinism and is sort of like how the red eyes are because of the mutation ( it's been awhile I forgot the exact science )
Oddly enough I was looking into eye color yesterday. People with albinism may have "red" eyes because they have such little melanin that the part of the eye that should be colored is almost clear, showing the blood vessels in the eye. Making them look red
I've read something about purple. There's an actress with them.
I looked it up and the purple eyes are similar to why people have blue eyes, a lack of melanin in the eyes. So idk but maybe it's where there's enough of whatever makes it blue to form a hue over the red to make purple ?
