When I do a WoC's makeup, I generally use a color that's lighter than their own skintone, but not too jarring-using Shroom on a NW45 just doesn't do it for me.
Depending on whether your a cool or warm WoC, I'd go with something a bit more on the bronzier side, something subtle but something that catches the light. Era and Grain work nicely on darker skintones IMO; Nylon, Ricepaper, Motif, and even-if you want to be a bit daring-Amber Lights on a more medium complexion.
If you want just a highlight though, go for something subtle.
Just my opinions though.
