To discover which blush color is right for you, you'll need to know what your undertone is. Determining your undertone can be done through a few different processes. The easiest way to figure out your skin's undertone involves glancing at the color of your veins. Looking at your wrist, check to see what color they are in natural lighting. If they lean towards more purple or blue, then you have a cool undertone. Green veins are indicative of a warm undertone, while a mix means that your undertone is neutral.
If you're darker skinned, figuring out your undertone from your veins alone may be difficult. You can look at the different hues of your skin to know what your undertone is. When looking in the mirror, do you mainly see yellows and golds under the surface of the skin? You have a warm undertone. Meanwhile, seeing reds and purples means you have a cool undertone. The jewelry test also works to find your undertone: If you look better in gold jewelry, you lean warmer, whereas shining in silver indicates a cool undertone.
