Skin Tone & Colour Season Detector
A skin tone detector samples skin colour from four face zones to estimate undertone and colour season, then builds a palette of shades that harmonise with it.
- Your measured skin colour, undertone and season, down to sub-season
- A personal palette with colours to wear together and colours to avoid
- Your photo isn't stored; your colour read is saved to your profile
Quick answer
Four face zones. Your undertone and season.

Upload a photoHow it works
Choose a photo
Use a front-facing photo in daylight, without a filter or heavy makeup.
We find your face
Landmarks locate your forehead, both cheeks and chin, avoiding hair, eyes and lips.
We sample colour
Skin colour is measured in each of the four zones and combined into one measured skin colour.
You get your palette
Your undertone, season and sub-season lead to a palette, colour pairs, metals and colours to avoid.
The four colour seasons
| Season | Undertone | Depth | Sub-seasons |
|---|---|---|---|
| Spring | Warm | Lighter | Light Spring · Bright Spring · Warm Spring |
| Summer | Cool | Lighter | Light Summer · Soft Summer · Cool Summer |
| Autumn | Warm | Deeper | Soft Autumn · Deep Autumn · Warm Autumn |
| Winter | Cool | Deeper | Deep Winter · Bright Winter · Cool Winter |
How this was analysed
How we handle your photo
What happens from the moment you choose a photo:
Your photo is resized and its location and camera metadata removed before anything is sent.
Face landmarks are located in your browser. If your browser can't, they are found on our server instead, by our own model or Amazon Rekognition.
The photo is sent once over an encrypted connection to check lighting and sharpness, and for colour tools to sample your skin. It is held in memory for that request and never written to disk or a database.
The measurements from your read, saved to your profile, which works without an account. Export or delete them any time.
Your photo is never used to train models. We don't keep it, so it can't be.
How we check our method
FaceAuraAI publishes its method, a rule check anyone can re-run and its bias notes — not scan totals or accuracy percentages. Each result carries a confidence label based on that photo's quality and how clear-cut the result was.
Stated selection biases
- Selfie uploaders who choose to use FaceAuraAI tools
- Front-facing photos with sufficient landmark confidence
- Landmarks found in the browser where it can, on the server where it can't
- English-first marketing traffic until locale depth catches up
- No age, region, or ethnicity stratification unless explicitly sampled and labeled

Frequently Asked Questions
Is the skin tone detector free?
Yes. Guests get 2 free reads a day, and a free account gets 5 a month. The limit is checked before you choose a photo, so you never upload and then hit a paywall.
What is an undertone?
Your undertone is the colour beneath the surface of your skin: warm (golden, peachy), cool (pink, blue) or neutral. It stays the same when your skin tans, which is why it guides colour choices better than depth alone.
What is a colour season?
A colour season groups colours that suit a combination of undertone and depth. Spring and autumn are warm, summer and winter are cool; each has three sub-seasons that narrow the palette further.
Why does lighting change my result?
Warm indoor light pushes skin towards warm, and shade or screens push it towards cool. Daylight from a window, facing the light, gives the most faithful skin colour.
Can I tell you my season instead?
Yes. If you already know your season you can set it on your profile. We show which one you declared and which one we measured, and never overwrite your answer.
Do you store my photo?
No. Your photo is used for this one read and then discarded; it is never written to disk or a database. What we keep are the measurements, saved to your profile, which you can export or delete at any time.
How reliable is the result?
Every result comes with a confidence label based on the quality of your photo: lighting, sharpness, head angle and how many landmarks were measured directly. We don't publish a single accuracy percentage, because it would depend on photos we haven't seen. A straight-on photo in even light gives the most reliable read.
