But that is the thing, foundation on its own does not give colour but suppose to match your skin. Its blush or bronzer that gives the colour. People think they look too pale or washed out when match to their true skin shade.
Yes I was just about to say the same, your foundation should match what your skin colour is - not what you want your skin colour to be. Blusher and/or bronzer add the warmth. I think people really underestimate the difference blusher can make.
Ali Young was put in a slightly darker BM foundation for one of their shows and she said she was going for a warmer look. She didn't look warmer, she just looked like she was wearing a foundation that was too dark for her. Why do women think this looks good? It stands out like a sore thumb. (Ali Young is a bad example I know, as her make up generally looks terrible, but I couldn't think of anyone else as an example)
