are there ever many blondes in new superhero films?

Captain Marvel, Black Widow's sister, Dr. Strange's girlfriend, the original Wasp, Pepper Potts is more of a reddish-blonde, but played by a blonde actress, Black Widow dyed her hair blonde in some of the films, Sharon Carter... and that's just a handful of recent MCU films. It seems like blonde women are overrepresented in superhero films, as they are in all films.
