About this tool
Capture from your webcam or upload a photo to identify surface tone, Fitzpatrick type, and get personalized wardrobe and cosmetic color advice.
The Skin Tone Analyzer reads a webcam frame or uploaded photo, locates your face with a TinyFaceDetector model, samples a 50x50 pixel patch on the cheek, and averages it into a single skin colour it reports as HEX, RGB and HSL. It then converts that colour into two labels: an undertone taken from the hue angle (roughly 14-36 degrees reads warm, below 14 or above 320 reads cool, anything else neutral) and a Fitzpatrick type from I to VI taken from the lightness value. It is for anyone matching foundation, choosing wardrobe colours or picking a jewellery metal who wants a measured starting point instead of a guess in a shop mirror.

Face detection places the sample box at about 65% across and 60% down the detected face, so hair, background and clothing do not skew the average.
You get HEX, RGB and HSL for the sampled patch, so you can paste the value into any shade-matching chart yourself.
The same sample drives both the warm/cool/neutral undertone call and the Fitzpatrick I-VI classification, so the two never contradict each other.
It converts the averaged cheek colour to HSL and reads the hue angle: about 14-36 degrees is reported as warm, below 14 or above 320 as cool, and everything in between as neutral. Because hue shifts with lighting, a photo shot in daylight will classify more reliably than one under a warm indoor bulb.
The Fitzpatrick scale is a six-step classification (Type I to Type VI) describing how skin responds to sun, from always burns and never tans to deeply pigmented and never burns. This tool assigns it from the lightness channel of your sampled colour, with the brightest readings mapping to Type I and the darkest to Type VI. A clinical Fitzpatrick assessment also asks about your burn and tan history, so treat this as informational and see a dermatologist for anything sun-safety related.
Yes, uploads work the same as a webcam capture and the size limit is 15MB. A straight-on, evenly lit shot with your cheek clearly visible gives the most stable sample, since the analyser reads one small patch rather than the whole face.
It follows the undertone result directly: warm undertones return yellow gold, cool undertones return silver and white gold, and neutral undertones return a balanced gold-and-silver suggestion. It is a starting point drawn from your measured hue, not a rule, so try both against your skin before buying.
