Why is there no word for women with black hair ?

@WaryWitchWandering weird to connect an animal that has no hair to a hair color... now i am imagining a hairy bird....

@Strawberrry apparently because this:
“Hair is naturally reflective, so black hair is not completely dark in bright light. However, the darkest shade will not have a warm, neutral tone but a sheen which can seem almost blue, like the iridescence of a raven's wing; hence, sometimes referred to as raven-black”
