What Tone & Fit does

Tone & Fit reads three things from one photo of your face: your undertone (warm, cool, neutral or olive), your depth, and your contrast. It uses them to place you in one of the 12 seasons of seasonal color analysis, then turns that season into practical advice: the clothing colors to wear and to skip, makeup shades, hair colors and the jewelry metals that suit you.

Each season's palette has 38 named shades, grouped into statement colors, everyday midtones, neutrals and accents. The palette pages on this site are built from the same shade data the app uses, so a color you read about here is the color the app shows you.

What is free and what is paid

The web tool is free: it names your season from one selfie, with no sign-up. In the iPhone and Android apps, the first scan is free with no account and shows your undertone, your best metals and a starter set of your colors. Your season, your full palette and the makeup and hair guidance in the app are an optional upgrade. Current prices are shown in the app stores rather than on this site.

What happens to your photo

Your photo is resized on your device, then sent over an encrypted connection to our analysis service, a Cloudflare Worker, which passes it to Google's Gemini API for the color analysis. The photo is analyzed, then discarded, never stored by us: it is processed in memory for your request and we keep no copy. The full detail, including what usage data we do keep, is in the privacy policy.

Who builds it

Viral Tandel built Tone & Fit after watching his sister realize she'd been wearing the wrong color season for 30 years. He designs and builds the app and the web tool and runs this site, and every article here is published under his name, so he is the person to write to about any of it.

Elsewhere: his developer pages on the App Store and on Google Play.

How the guides are written

• The guides explain the 12-season system as it is commonly taught: undertone, value (how light or deep) and chroma (how clear or muted).
• Celebrity seasons are given as the readings most often cited, not as verdicts. Nobody here has draped those people in person.
• Where we compare color analysis apps, we say plainly that we built one of them.
• Every guide and blog post shows when it was published and, if it has changed since, when it was last updated.
