To choose the correct color, test a little on the jaw line. Try to do this in natural light if possible. We recommend beginning with our Natural and Amber mineral foundations because they have the same value, but Natural has a pink undertone and Amber a yellow. It will be easy to see whether to go lighter, darker, more pink or more yellow. Our mineral makeup is much more forgiving than other makeup – one shade will suit a wide variety of skin tones – because our mineral foundations interact with light in ways that adjust to your own skin tone.
