They used to call them Octaroons.
An octoroon was someone who was 1/8 black and 7/8 white. Not to be confused with a quadroon, who was 1/4 black and 3/4 white. Fortunately, those names are out of date as we don't feel the need to go into such detail over a person's racial makeup
In colonial Latin America, they had hundreds of names each describing a person's particular mix of African, Spanish, and Native American blood.
