non-white person
A direct compound meaning a person who is not white. Often used in discussions of race and ethnicity, especially in contexts where whiteness is the default or majority. Can carry a slightly formal or sociological tone.
In that region, non-white people sometimes face discrimination.
Compound of 非 (hi, 'non-') and 白人 (hakujin, 'white person'). The prefix 非 is productive in modern Japanese for forming negative or opposite nouns.
