Anyone dealing in color like a painter, hair colorist or a makeup artist know that the best way to hide a color you don’t like, is to hide it with another color. Undereye circles got you? A breakout? You’ll find that concealers and foundations do a great job at making your skintone look better but in actually trying to hide skin discolorations, you’ll find that a few hours into it concealing work either looks like it’s gone, or went darker and grayer.
That’s because ‘skin colors’ (i.e. yellow) do a great job at evening out skin tones. But it doesn’t do much to hide or tone down actual colors in your skin that you want to hide. Only other colors can hide color.
