I've looked at several family photographs and I can't find any trait that identifies him as a person of colour, or am I misunderstanding the answer?
Are you talking about @aussieninja ? I am talking about me. I am a "person of color" ;)
I knew a young woman with African American features who was identified mainly by the fullness of her lips.
What makes the "African" or "American" part of the features? It is funny to consider, isn't it?
Technology is a big part of it, but it isn't just ease of use, it is also opportunity to avoid.
