What is 12-season color analysis?

Short answer: 12-season color analysis is a method for finding which clothing, makeup, and hair colors flatter you, based on your natural undertone, value (how light or deep your coloring reads), and chroma (how bright or muted your features are). It splits the four classic seasons — Spring, Summer, Autumn, Winter — into three sub-seasons each, so instead of "you're a Winter" you get a precise placement like Cool Winter or Bright Spring, with a curated palette to match.

The Method

The 12-season system, guided.

Personal color analysis used to mean a stylist, a $300 in-person session, and a week of waiting. Tonebook brings the same framework (Spring, Summer, Autumn, Winter, three sub-seasons each) into a guided photo analysis grounded in the Sci\ART 12-season tradition.

01
A subject holding a rust drape at the collarbone in soft natural daylight — the kind of selfie Tonebook reads in step one
Step one

One selfie, north-window light.

Front camera, natural light, no filter. The app guides you through framing before analysis.

02
Step two

Your undertone direction.

The app evaluates visible skin, hair, and eye color cues from a clear photo in neutral light. Warm, cool, neutral, or olive, with confidence guidance when the result is close.

03
Step three

Your season, located.

Twelve seasons, one primary result. The app also shows an adjacent season and confidence guidance when the result is close.

04
Step four

Your full palette.

Twelve best (above), plus neutrals and use-carefully colors — curated for clothing, makeup, and hair. Exportable, shoppable, swatched against the brands you already wear.

What's Inside

Four ways your colors come to work.

Once Tonebook reads your season, it stays in the loop. Every outfit suggestion, every shopping rec, every Style Check is filtered through the palette that actually flatters you.

Daily ritual + Style Check

Today's color rotates from your palette. Your outfit pick adapts to the actual weather. Style Check lets you snap any item — lipstick, top, accessory — to instantly know if it matches.

Inclusive color analysis

Built for every undertone.

Traditional color analysis was often demonstrated on a narrow range of skin. Tonebook treats skin depth and undertone as separate signals and shows confidence when a result is close, rather than defaulting deeper skin to one season.

Why Tonebook

The case for
structure.

Tonebook turns a photo result into practical palette guidance.

01 — Transparency

A single label can hide a close call. Tonebook shows it.

Confidence guidance and an adjacent-season comparison make uncertainty visible instead of presenting every photo result as absolute.

02 — Speed

In-person consults require an appointment. Tonebook starts with one clear selfie.

A structured 12-season photo flow with no appointment or travel.

03 — Personal

Pinterest boards are someone else's palette. Yours is yours.

Personal palette guidance you can use in your shopping list, closet, and camera roll.

04 — Color-aware outfits

Cladwell builds capsules. Tonebook builds capsules in your colors.

Other wardrobe apps prescribe outfits without knowing your skin tone. Every Tonebook suggestion is filtered by your actual season — the unique wedge no other app has.

Common questions

Asked, plainly.
Answered, plainly.

Ordered by what people actually worry about, not by what we'd like to lead with.

Q · 01

Do my photos leave my phone?

Yes, when you choose an online analysis. In the iPhone app, Live AI sends the prepared photo, your profile answers and, when available, derived color measurements through Tonebook's Supabase service to OpenAI. A prepared photo is not guaranteed to contain only a face crop. The browser analyzer separately resizes your selected image and sends it through Tonebook's Vercel endpoint to OpenAI. The browser quiz does not require a photo. See the Privacy Policy for processing and provider-retention details.

Q · 02

Are my photos used to train AI?

Tonebook does not offer a photo-training program or a training-data toggle. OpenAI's API data policy states that API inputs are not used for model training by default. That is separate from provider retention for safety and abuse monitoring; it does not mean every uploaded image is immediately deleted everywhere.

Q · 03

How accurate is the season placement?

Tonebook follows the Sci\ART 12-season tradition and evaluates undertone, value and chroma from the photo instead of asking you to self-rate vein color. Borderline results are flagged with a confidence label and adjacent-season callout, and depth is treated separately from undertone. If a placement looks off, retake the photo in neutral light and compare the adjacent season.

Q · 04

What's free vs. Tonebook Pro?

Free preview: your season and up to 10 colors. Pro Annual (3-day free trial): wardrobe tracker, outfit generation across nine occasions, Style Check, weather-aware daily outfits, gap analysis, season-based beauty guidance, and palette exports. Weekly, annual, lifetime, one-time report, and bundle options are available; current localized prices are always shown in the app before purchase. Subscriptions auto-renew until canceled in iPhone Settings → Apple ID → Subscriptions.

Q · 05

Can I refund Pro?

Yes. Refunds are handled by Apple at reportaproblem.apple.com. Apple's standard policy is generous within 14 days of charge.

Q · 06

Which devices and skin tones are supported?

iPhone XS and newer, iOS 17+. The analysis treats skin depth separately from undertone and shows a confidence label instead of claiming certainty. If a placement looks off, use a clear photo in neutral daylight and compare the adjacent-season result.

Q · 07

Will there be an Android version?

Not currently. Tonebook is focused on the iPhone experience; no Android release date has been announced.
