Generalizations such as those don't work. Skin tones are so widely varied that the best rule to follow is to look at yourself and the fabric in a mirror. And, yes, I know this is a somewhat maverick p.o.v. which may upset many, but hey. I tells it like I sees it.
And is absolutely correct. There are large variations in Chinese skin tones alone, (happens when there are 1.6 billion of you), not to mention other Asians. Sam goes for all other races and ethnicities, sand especially for Americans (blacks and whites in particular), who are usually mixes of a whole bunch of ethnicities. There are some generalizations to be made, but these are only minimally useful. The only way to tell if a particular color is for you is to look in the mirror. Hmmm, I guess 30 years in the business gives you some insights one these things, huh
