Not that it’s impossible in reality but you’re more likely to find somebody with black hair and brown eyes or even black hair and green eyes. Black hair and blue eyes is a strangely common occurrence in superhero comics (and by extension almost any cartoon in colour) due to printing and colouring quirks beforehand.
One could have blond hair and brown eyes, not just with some Europeans but most especially with some Aboriginal Australians and Melanesians. It’s been attempted in comics, just not so often and the only one that I can think of is Zip Kid from Young Heroes in Love.
Dark brown hair and blue eyes is a better, more realistic compromise which is more commonly done in live action. But there aren’t that many black haired superheroes consistently shown with brown eyes and dark skin, it currently defaults to dark brown for some reason.
