Warm vs Cool Hair Colors: How to Tell What Colors Actually Work For You

The key to flattering hair color isn't the shade itself, it's how well it matches your skin's undertones. Understanding whether you have warm or cool undertones helps you choose colors that enhance your natural features rather than clash with them.

This guide covers simple methods to identify your undertones, explains the distinction between warm and cool hair colors, and provides recommendations for selecting shades based on your undertone category. Whether you prefer warmer golden tones or cooler ashy shades, matching your hair color to your natural coloring creates a more harmonious, flattering result.

How to Tell if You Have Warm or Cool Undertones

These three quick and easy tests use everyday observations like checking your vein color, testing jewelry against your skin, and examining how white fabric looks next to your face to reveal whether you're warm, cool, or neutral toned.

The Vein Test

Flip your wrist over and check out the veins on the inside of your arm in natural light. If they look greenish, you've got warm undertones. If they appear blue or purple, you're team cool. See both? Lucky you! You're probably neutral, which means you can rock pretty much anything.

The Jewelry Test

Think about which metal makes you feel like the main character. Does gold jewelry make your skin glow? Warm undertones. Does silver jewelry make you look more radiant? Cool undertones. If both look equally good, you're likely neutral.

The White Paper Test

Hold a piece of pure white paper next to your face in natural lighting. If your skin looks yellowish or peachy against the paper, you have warm undertones. If it looks pink, red, or bluish, you're cool-toned. This one's a game-changer!

What Is The Difference Between Warm and Cool Hair Colors?

The key difference between warm and cool hair colors lies in their underlying pigments, with warm shades leaning toward golden and red bases while cool shades are built on ashy, blue, and violet foundations.

Warm hair colors have golden, orange, or red undertones. Think sunset vibes like all of those gorgeous peachy, copper, fiery red, and honey blonde shades that feel like sunshine.

Cool hair colors have blue, violet, or green undertones. These are your icy platinum blondes, ashy browns, jewel-toned purples, and those dreamy blue-greens that give off major mermaid energy.

The magic happens when you pair your skin’s true undertones with hair colors that match. Warm undertones + warm hair colors = chef's kiss. Cool undertones + cool hair colors = absolute perfection.

If you're working with warm undertones, you want colors that enhance that natural golden glow. The right warm hair color can take you from boardroom to dance floor, or anywhere in between.

Corporate baddie with an edge? Ginger Flare is that rich, warm copper that says professional but make it interesting. Poison brings deep red tones that command attention in the best way, perfect for when you want to be taken seriously but refuse to blend in.

All-night raver or festival regular? Go bold with Sunset Orange; it's vibrant, energetic, and absolutely unapologetic. Cosmic Sunshine delivers that warm yellow that glows under any lighting and matches your high-energy lifestyle.

Romantic bookworm? Virgin Pink gives you those bold pink tones that feel whimsical and grounded at the same time. It's subtly warm without screaming for attention, perfect for coffee shop hangs and forest walks.

Adventurous creative type? Warm undertones can absolutely rock blues and greens. Aquamarine has warmer teal undertones that complement your golden base while letting you experiment with cooler tones.

The key is choosing colors with warm bases. Even when you venture into blues or greens, look for versions with golden or peachy undertones that harmonize with your natural warmth.

How to Choose Hair Colors for Cool Undertones

Cool-toned individuals shine brightest in hair colors that mirror their skin's natural undertones, which means gravitating toward ashy blondes, cool-toned browns, platinum hues, and jewel-inspired shades like burgundy or violet that create a harmonious, flattering contrast with your complexion.

Medieval fantasy lover? Emerald Fortune gives you that enchanted forest green that’s rich and otherworldly.

Cool girl who keeps it effortless? Poseidon is that perfect cool-toned blue that looks intentional without trying too hard. It's bold enough to be interesting but balanced enough to feel like it's just part of who you are.

Creative maximalist or artistic rebel? Purple Madness is vibrant, cool-toned violet that refuses to apologize. Iris Green sits in that unique teal-meets-green space, perfect for anyone who thinks inside the box is boring.

Moody intellectual or nighttime wanderer? Go for the deeper shades. Witches Delight and Sorceress both deliver that dark, contemplative vibe that pairs well with vintage books and late-night city walks.

The secret for cool undertones is embracing ashy, blue-based, or violet-based colors. These shades complement your natural coloring and make your skin look luminous rather than washed out.

How do you know if you look better with cool or warm hair?

Do the vein test: Check the veins on the inside of your wrist. Greenish veins = warm undertones, bluish/purple veins = cool undertones.
Try the jewelry test: Notice whether gold or silver jewelry looks better on you. Gold = warm, silver = cool.
Use the white paper test: Hold white paper next to your face in natural light. Yellowish/peachy skin = warm undertones, pink/red/bluish skin = cool undertones.

How do I know if warm or cool colors look good on me?

Identify your undertones using the three tests above (vein, jewelry, and paper test).
Match your undertones to your hair color: Warm undertones look best with warm hair colors (reds, coppers, peachy pinks, warm yellows). Cool undertones look best with cool hair colors (purples, blues, cool greens, ashy tones).
Test it out: Try on wigs or use virtual hair color apps to see how different tones look against your skin before committing.

How to tell what hair color suits you?

Start with your undertones: Use the vein, jewelry, and paper tests to determine if you're warm or cool-toned.
Consider your lifestyle: Are you corporate, creative, low-maintenance, or high-energy? Choose a color that fits your daily routine.
Think about maintenance: Bolder colors require more upkeep, while softer shades are easier to maintain.
Match your personality: Pick a shade that reflects your vibe—whether that's moody intellectual, all-night partier, or coastal chic.

How do I tell which colors look best on me?

Check your undertones first: This is your foundation for choosing any color, including hair color.
Do the fabric test: Hold different colored fabrics or clothes near your face in natural light. Colors that make your skin look bright and healthy (not washed out or dull) are in your color family.
Look at your current coloring: Notice which colors in your wardrobe get you the most compliments—those are likely in your undertone family.
Apply the same principle to hair: Once you know which color family flatters you, choose hair colors with similar undertones.
