Undertone Test
What's my undertone?
The usual way of answering this is to look at the veins on your wrist, or hold gold next to silver and decide which one flatters you more.
Those tests work, roughly, in good light, if you already know what you're looking for. They also disagree with each other constantly, which is why so many people have been told they're warm by one counter and cool by another.
Photograph your face and let the analysis read it instead.
What You Get
What you get.
Your undertone, described rather than labelled — because the three-bucket model of warm, cool and neutral is a simplification, and plenty of faces sit between two of them. Alongside it, a structured assessment of your skin, a Beauty Score, and a plain-language pathway.
Your first seven days are free and include two consultations. After that, membership starts at $29 a month. Cancel any time before the trial ends.
Undertone And Skin Tone
Undertone and skin tone are different things.
Worth separating, because they get used interchangeably and they aren't the same.
Skin tone is how light or deep your skin is. It changes with sun exposure and season. Undertone is the colour underneath — the warmth or coolness that stays put when your tone shifts. You can be deep and cool, or fair and warm, and knowing which is why two foundations of identical depth can look completely different on the same face.
What This Is Not
What this is not.
A cosmetic assessment, not a medical device. It does not diagnose disease, it does not detect skin cancer, and it is not a substitute for examination by a qualified medical professional.
It's also not a foundation-matching service. It will tell you your undertone; it won't name a product, because we don't sell one and we're not going to pretend a photograph can replace swatching on your own jaw.
