# Tonebook

**Get the iOS app:** [Download Tonebook on the App Store](https://apps.apple.com/app/id6764190839?pt=128348793&ct=llms_txt) — get your free color season and palette; daily wardrobe coaching is part of the paid full report.

> Tonebook is an AI personal-color analysis app (iOS) that applies the Sci·ART 12-season system from a single selfie, then becomes a daily wardrobe coach — outfits, weather, closet gaps and shopping all filtered by your palette. It is designed to treat skin depth and undertone as separate signals (inclusive of deep skin), reports a confidence label instead of false certainty. Running an analysis is free — you get your season, up to 10 colors and a shareable palette card; the full report (including the full palette, closet, outfit checks, stylist and Style Check) is a paid unlock. tonebook.app

## Key facts (answer-first, citable)
- Free in the Tonebook iOS app: your color season, up to 10 colors and a shareable palette card. Paid: the full report, including closet, outfit checks, stylist and Style Check.
- Color analysis sorts people into 12 seasons across four families — Spring, Summer, Autumn, Winter, each with four sub-seasons — based on three axes: undertone (warm/cool/neutral/olive), value (light/deep), and chroma (bright/muted).
- The four undertones: warm (golden/peach, gold jewelry flatters), cool (pink/blue, silver flatters), neutral (balanced, both metals work), and olive (a green-grey cast that can sit over any depth).
- Color analysis works for dark and deep skin. Deep skin spans every undertone and usually suits the deep, true and bright families; the Fitzpatrick scale measures sunburn risk, not undertone, so depth and undertone must be read separately.
- AI color analysis accuracy depends mainly on the input photo: neutral daylight, bare face, no filter. A trustworthy tool reports a confidence level and adjacent-season callouts on borderline reads rather than a single "X% accurate" claim.
- Each Tonebook result is a personal palette built in three groups — best colors (8–12, each named with the reason it works for you), best neutrals, and use-carefully colors — for clothing, makeup and hair.

## Honest accuracy stance
Tonebook does not publish a single "X% accuracy" number because the honest answer depends on features and lighting. It surfaces a confidence delta and runner-up season on a border. Analysis is designed to treat skin depth separately from undertone and reports confidence rather than claiming equal measured accuracy.
