Yes, say you have a yellowish to olive skin tone... you wear a red wig.... the wig will look more orange and the skin will look more white. It's a strange thing and a lot of it has to do with the lighting as well. I used to work at a paint store and had to match colors and it's crazy how a small amount of green will neutralize any red. It's a good thing to keep in mind when you are coordinating colors.
