The Method
The 12-season system, measured.
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, four sub-seasons each) into a 60-second analysis grounded in the Sci\ART 12-season tradition.
01
portrait · neutral light
Step one
One selfie, north-window light.
Front camera, natural light, no filter. The app guides you through framing in under 20 seconds.
02
Step two
Your undertone, isolated.
The app reads skin, hair, and eye pixels in sRGB and converts to perceptual color space (Lab, OKLCH) to separate true undertone from ambient lighting cast. Warm, cool, or neutral. Measured, not guessed.
03
Step three
Your season, located.
Twelve cells, one match. We place you on the wheel: Soft Autumn, Cool Winter, Light Spring. With the reasoning shown alongside.
04
Step four
Your 12-color palette.
Curated for clothing, makeup, and hair. Exportable, shoppable, swatched against the brands you already wear.

How it actually works →
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.
02 — Build
Wardrobe + AI outfits, in your colors
Add clothes via camera. Tonebook extracts dominant colors and tags by category, then generates outfits for nine occasions — workwear, weddings, vacation, and more — picked from your closet, in your palette.
03 — Wear
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.
04 — Shop
Gap analysis + smart shopping
Tonebook sees the gaps in your closet and suggests three picks at three price tiers, all in your palette. Wallet card export for in-store browsing. Hair, makeup, and accessories guidance per season.
Proof
Built openly. Tested patiently.
Tonebook just shipped. We're not pretending to have hundreds of reviews we haven't earned yet. We're inviting the first wave of users to put the system through its paces. Real reviews, real palettes, real season placements published as they come in.

Why Tonebook
The case for
measurement.
We're not the only color app. We're the one that doesn't guess.
01 — Accuracy
Free five-minute quizzes guess. Tonebook measures.
We sample real pixels under modeled light. Quizzes ask you to self-rate vein color in your kitchen.
02 — Speed
$300 in-person consults take a week. Tonebook in 60 seconds.
Same 12-season framework, machine-read from a single selfie. No appointment, no driving.
03 — Personal
Pinterest boards are someone else's palette. Yours is yours.
Twelve curated colors based on your actual undertone. Exportable to your shopping list, your closet, your 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. Tonebook every 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?
Pre-processing is on-device. Only the cropped face crop and the derived color samples are sent for analysis, encrypted in transit. Selfies are processed in-flight and not retained on our servers. See the Privacy Policy and Biometric Disclosure for the full data flow.
Q · 02
Are my photos used to train AI?
Not without explicit opt-in. The training-data toggle is off by default, lives in Settings → Privacy, and you can revoke consent at any time. Opted-in photos are anonymized and stripped of EXIF metadata before they reach any training set.
Q · 03
How accurate is the season placement?
Tonebook just launched, so we don't have published agreement data yet. The model is calibrated against the Sci\ART 12-season tradition; we're collecting structured feedback from the first wave of users and certified human analysts and will publish a real accuracy figure once the dataset is large enough to mean something. You can request a re-analysis with a new selfie any time on Plus.
Q · 04
What's free vs. Tonebook Plus?
Free: one full color analysis, your season, your 24-color palette. Pro ($59.99/year, with a 7-day free trial): wardrobe tracker (add clothes via camera, auto-extract dominant colors), AI outfit generator across nine occasions (workwear, weddings, vacation, date, gym, more), Style Check (snap any item — lipstick, top, accessory — to instantly know if it matches your palette), weather-aware daily outfits, gap analysis with three-tier shopping picks, makeup + hair + accessories guidance per season, and palette exports for in-store browsing. Other tiers available: Pro Monthly $9.99, Lifetime $129.99, Starter Report $6.99 one-time. Subscription auto-renews until canceled in iPhone Settings → Apple ID → Subscriptions.
Q · 05
Can I refund Plus?
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 16+. The model is trained on a deliberately diverse dataset spanning Fitzpatrick I–VI; if you ever feel your placement is off, send the analysis ID to support and we'll route it to a human reviewer.
Q · 07
Will there be an Android version?
Not on the v1 roadmap. We're focused on getting iOS exactly right; Android is on the table for late 2026 if demand justifies the parallel calibration work.
