Every question shifts your recommendation. Here's the full list - same order as the live quiz above.
Warm (gold, peach, yellow tones - veins look green), cool (pink, red, blue tones - veins look blue/purple), neutral (mix of both), or not sure. Skin undertone is the single biggest predictor of which hair colors will flatter you.
Brown / hazel, blue / gray, green / hazel-green, or amber. Eye color narrows the palette by either complementing or contrasting your hair shade.
Black, brunette, blonde, red / auburn, or gray / salt & pepper. Where you start determines how much of a lift, deposit, or correction the new color needs.
A subtle 1-2 shade change from current, a big transformation, gray coverage, or just having fun. The goal sets the size of the jump - subtle stays close, fun goes wild.
Classic / professional, edgy / bold, sun-kissed / natural, warm / cozy, or cool / icy. Vibe is the personality of the color - it's why two people with the same skin tone can want completely different shades.
Hair color is the biggest accessory you wear every day. The right shade lights up your skin; the wrong one washes you out, no matter how flattering it looked on the box.
Skin has a constant warm or cool tint underneath surface pigment - that's your undertone. Look at the inside of your wrist: greenish veins point to warm; blue or purple veins point to cool; a mix is neutral. Pale, medium, deep - undertone applies to every skin shade.
Warm hair colors (honey, copper, golden brown, auburn) read as friendly extensions of warm skin. Cool hair colors (ash, platinum, jet black, burgundy) sit beside cool skin like complementary shades on a paint chip. The harmony is what makes the color "look natural" instead of "off."
Cool platinum on warm skin can look gray-greenish in sunlight. Brassy gold on cool skin can pull orange. The hair didn't change - the contrast against your skin is what creates the "wrong" effect. Most "I don't suit blonde" stories are really "I picked the wrong temperature of blonde."
After undertone, your eye color tightens the recommendation. Brown eyes glow brighter against warm caramels and chocolates. Blue and green eyes pop against cool, deeper hair. Amber eyes love rich auburn and copper. The quiz uses both signals together.
Even with the right rules, no two people look the same. That's why the quiz hands you 5 starting shades and lets the AI render each one on your actual photo. The "pretty close" answer becomes "I love this one" the moment you see it on your face.
Warm undertones glow with shades that share their golden, peachy, or coppery base. The richer the warmth, the better.
WARM CLASSICS
WARM REDS
WARM BRUNETTES
Cool undertones come alive against ashy, smoky, or icy hair colors. Anything with a blue, violet, or silver bias will flatter.
COOL BLONDES
COOL DARKS
COOL REDS
Neutral undertones are the most versatile - shades from either end of the warm-cool spectrum can work, especially anything sitting in the middle.

Once undertone narrows the palette, eye color is the second filter. Pairing them right is what makes a color "pop" instead of just "fit."
| Eye Color | Best Hair Colors |
|---|---|
| Brown / Hazel | Caramel, chestnut, chocolate brown, honey balayage, auburn - rich warm tones make brown eyes glow. |
| Blue / Gray | Platinum blonde, ash blonde, jet black, dark brown, soft burgundy - cool, contrast-heavy shades brighten the iris. |
| Green / Hazel-Green | Auburn, copper, deep red, chestnut, mahogany - warm reds and browns make green eyes pop. |
| Amber | Copper, ginger, dark chocolate, honey, balayage honey - shades that share the eye's warm gold base. |
| Light blue or pale gray | Soft icy blondes, light ash brown, silver, dusty rose tones - low-contrast cools keep the eye luminous. |
Everything people ask before taking the hair color quiz for the first time.
Answer 5 short questions about your skin undertone, eye color, current hair color, change goal, and the vibe you want. The quiz maps your answers to 5 shade recommendations from Trimsy's hair color library, then lets you upload a photo to see each one rendered on yourself in seconds.
Warm undertones (gold, peach, yellow skin tones, green-looking veins) are flattered by warm hair colors: honey blonde, golden blonde, caramel, chestnut, auburn, copper, ginger, and rich chocolate brown. Avoid ash and platinum tones, which can wash warm skin out.
Cool undertones (pink, red, blue skin tones, blue-purple veins) glow next to cool hair colors: ash blonde, platinum blonde, ash brown, jet black, blue-black, burgundy, silver, and cool dark browns. Skip golden and orange-warm shades, which can clash with cool skin.
Neutral undertones (a balance of warm and cool) are the most versatile: medium brown, soft balayage, neutral blonde, light brown, chestnut, and most shades in the middle of the warm-cool spectrum all work. Use the quiz plus the AI try-on to see which neutral-friendly shade you actually prefer.
