That article was written back before I became a color analyst, before I had worked out my perfect vocabulary in this regard. If I were to write this today, it would be called “Unnatural color doesn’t work IRL”. The dark elements in your coloring require a much darker lip to look natural than Reese Witherspoon does. I think that I was reacting to the fact that too many light women wear a dark lip, and in its severity, it looks again.
I think we have different taste about pale lips on dark women. On the reverse side, when Keira wears a pale, flesh-toned, nude lip, she looks utterly flat, like that photo where she appears to be wearing concealer. I don’t care for it and can’t see it on a 45 year old woman. I guess that my best generalization should be that lips that are about the same degree of intensity as the hair is most balanced looking. But note that none of this has to do with the skin color – meaning that Reese and Keira could well wear the same foundation, but it’s their undertone and the other elements of their coloring that are balanced and harmonized when choosing makeup.
