How do I know my skin tone and undertone? In natural light, check the appearance of your veins beneath your skin. If your veins appear blue or purple, you have a cool skin tone. If your veins look green or a greenish blue, you have a warm skin tone. If you can’t tell whether or not your veins are green or blue, you probably have a neutral skin tone.
How do you define your undertone? If you can see your veins, you may be able to use their color to identify your undertone. For example, if your veins look greenish, then you may have warm undertones. People with blue or purplish-looking veins usually have cooler undertones.

“You have cool undertones if you can see blue veins in your skin. If your veins appear green on the skin (olive), you’re warm. Neutral is a mixture of both warm and cool undertones,” he explains.
Is my undertone yellow or red? Warm: If the base tone of your skin is yellow or gold, you have warm undertones. Cool: If you see hints of blue, pink or red, then you have cool undertones. Neutral: If there’s a mixture of both warm and cool hues, or your undertone is the same color as your actual skin color, then you fall into the neutral category.
