I don't want to cause any arguments, so try to answer me in as close to a one-word answer as you can. Do people in America, outside of racially motivated killings, think of people in terms of being a person of color or person without color all the time? A few times I've heard Austin refer to someone as being a person of color, when I wouldn't have thought that it was notable at all. It might just be me being a person without color and Austin being an American person of color, but it's just not something I think about.
person of colour is the generally accepted term for non-white, and race is often relevant, but might appear irrelevant to white people concerning things like representation where it has never seemed to be an issue. i'm european, it's used a lot outside america too
