What Is an Undertone Test?
An undertone test identifies the true underlying color temperature of your skin - warm, cool, neutral, or olive. Unlike your surface skin tone, which can tan or fade, your undertone stays the same and affects which makeup shades look most natural on you.
How Traditional Undertone Tests Work (and Their Limits)
- Vein Color: Blue veins suggest cool undertones; green means warm. But mixed or hard-to-see veins can be confusing.
- Jewelry Test: Silver flatters cool undertones, gold suits warm. This can be subjective and influenced by personal style.
- White vs Off-White: Pure white clothing flatters cool undertones, off-white suits warm. Lighting and clothing color can mislead.
- Tanning: If you tan easily, you may be warm; if you burn, you might be cool. However, this isn’t reliable for everyone.
These manual methods can be inconsistent. For a more objective result, try the selfie-based test below.
