Skin tone is referred to as either warm or cool. Standing in front of a window, with natural light from the sun, make a fist and look at your inner wrist. What color are your veins of your inner wrist?
Signs of cool color toned skin are veins that are mainly blue, while mainly green toned veins are signs of a warm color toned skin. If your veins are a mix of blue and green, then this is a sign of a neutral toned skin.
Warm toned skin colors look best in yellow-based colors
Cool toned skin colors look best in blue-based colors
Cool toned skin color – Your eyes are usually blue or blue/gray and your natural hair color is Blonde, Brown, or Black. Wrist veins, in natural light, will appear blue and your skin will have definite pinkish or blue undertones. You burn easily in the sun, or burn, then turn tan.
Warm toned skin color – Your eyes are usually Brown, Green, or Hazel. Wrist veins, in natural light, will appear green, and your skin will have yellow, peach, or olive undertones. Your natural hair color can be Black, Brown, Red, Strawberry Blonde, Auburn, or Blonde. You usually tan without a burn in the sun.
To even out your skin tone, instead of choosing a color that matches your skin tone, use a color that is opposite of your skin tone. For example, if you have pinkish undertones, if you choose a foundation that is more neutral tone, like neutral light or neutral medium, you will block out some of the pink tone of your skin for a more neutral tone to your skin.
If, however, you choose a rose or red based foundation, you will have a color more matched to your skin color.
