We hear daily "a woman or color". One person here mentioned that Nikki Haley (parents are from India) is a woman of color.
What defines "woman of color?" Is there some scan gun that they put point at your head and defines the pigmentation?
I am mostly Northern European and my Columbian wife is as "white" or more so than I am. As she always complains about surveys or other things here in the US, they have Caucasian as one check box and Hispanic as another. What if you are both, white and speak Spanish. As she correctly argues, Hispanic is simply the language you speak.
I used to work with a guy who always called jokingly himself an African-American. He was born in Africa, South Africa, probably after some generations of the British rule. His skin was as white as a KKK hat. So was he a "man of color"?
In today's world, color is a very difficult thing to determine.
