Answer:
A lot of times, a natural redhead will have red pubic hair, probably a shade or two lighter or darker than the hair on their head. But many people with red hair may have blonde or light brown as well. Those who have dark red or auburn hair sometimes have brown or reddish brown pubic hair.
It's kind of like how some blondes have dark pubic hair.
Most people say that pubic hair is generally the same color as a person's eyebrows.
