What Is Your Skin Undertone? How to Find It and Choose Makeup That Flatters You

Undertone is the secret behind every makeup shade that flatters you, and the one most people get wrong. Here's how to read yours.

Undertone is the color beneath your skin's surface, and it's the reason a lipstick looks stunning on one person and washed-out on another. Unlike skin tone (how light or deep you are), undertone stays consistent regardless of whether you're pale in winter or tan in summer. Get it right and foundation, blush, lipstick, and even clothing suddenly make sense. Get it wrong and even expensive makeup looks off.

The Four Undertones Explained

Cool

Cool Undertone

Skin reads pink, red, or bluish. Silver jewelry flatters you more than gold. You burn before you tan. Cool undertones suit jewel tones, berry lips, rosy blush, and pink-based foundations.

Warm

Warm Undertone

Skin reads yellow, peachy, or golden. Gold jewelry flatters you more than silver. You tan easily. Warm undertones suit earth tones, warm corals and oranges, peachy blush, and yellow-based foundations.

Neutral

Neutral Undertone

Skin has a balanced mix of pink and yellow. Both gold and silver look good on you. Neutral undertones can wear the widest range of colors, including most nude and rose shades.

Olive

Olive Undertone

Skin has a subtle greenish cast, often with yellow or golden depth. Olive is its own category because it doesn't fit neatly into warm or cool. Olive skin suits muted greens, bronzes, warm reds, and golden-yet-neutral foundations.

5 Reliable Undertone Tests

  1. Vein test: Blue/purple wrists = cool. Green = warm. Teal/unclear = neutral or olive.
  2. Jewelry test: Silver flatters cool, gold flatters warm, both flatter neutral, gold and rose gold flatter olive.
  3. White paper test: Hold white paper by your face in daylight. Pink cast = cool, yellow cast = warm, greenish = olive, neither = neutral.
  4. Sun test: Burn-first, tan-rarely = cool. Tan-easily, burn-rarely = warm. Olive tans but can burn with a greenish cast.
  5. Color test: Hold a pure white and a cream shirt near your face. If white brightens you, you're cool. If cream warms you, you're warm.

Undertone Mistakes to Avoid

Assuming deep skin is always warmDeep skin can be cool, warm, neutral, or olive. Don't default to warm just because the skin is rich.
Confusing redness with cool undertoneSurface redness from irritation is not the same as a cool undertone. Look at the jawline, not the cheeks.
Using too-pink foundation on olive skinPink-based foundations turn ashy or grey on olive skin. Lean golden-neutral.
Ignoring undertone for blush and lipsA warm blush on cool skin looks orange; a cool berry on warm skin looks bruised. Match undertone across all color products.

Frequently Asked Questions

How do I know if I have warm or cool undertones?
Use the vein, jewelry, white paper, sun, and color tests. Blue/purple veins and silver jewelry point cool; green veins and gold jewelry point warm. If results are mixed or unclear, you're likely neutral.
Can my undertone change with a tan?
No. Your skin tone (depth) changes with a tan, but your undertone stays the same year-round. That's why undertone is the more reliable guide for choosing makeup shades.
What makeup suits olive undertones?
Olive skin suits golden-neutral foundations (never too pink, which goes ashy), warm reds and terracotta lips, peach and bronze blush, and bronze, gold, and olive eyeshadows. Avoid bubblegum pink and ashy cool tones.
Does deep skin always have warm undertones?
No. Deep skin can be cool, warm, neutral, or olive. Always test the undertone rather than assuming based on skin depth.
