Let's say I was educated to think of French people having white skins. In Paris this year for my first European visit, I was expecting to encounter many different groups of people. Would you feel better if I stated that I did notice that about half the people I saw in Paris did not look like I had been led to believe, via my 1960s Anglo public education, French people should look. Of course I had been taught that every one in France looks like (white) Vogue models or film stars.
To answer your question more directly, where I live most people do look alike. A person dressed in traditional African or Islamic dress DOES stand out. Not Asians, as we have had Chinese people living in Australia since the 19th century and Vietnamese since the fall of Saigon. The people in Brisbane who look Asian to me, tend to dress the same as me, before you comment on dress.
Where I live in white picket fence middle class Pleasantville suburbia, everyone has the same coloured skins. My seven-eighth British/one-eighth Maori tan is the same shade as the Punjabi lady I work with and all the Fijians at work. Those my age and older with pale white skins tend to be covered in freckles and age spots which also match my tan.
