§ 01 / How it works

An analysis, not
a horoscope.

Five to ten photographs, any phone, any lighting — a few in daylight if you have them. The model reads skin, eye, and hair against a calibrated set, then sorts you into one of twelve palettes with reasoning you can argue with.

01

Upload

Five to ten photographs. Natural light preferred, but not required. Faces visible, no heavy filters. We strip EXIF on ingest.

02

Calibrate

Each image is white-balanced against a reference chart embedded in the model. We isolate skin, lip, eye, and hair before sampling.

03

Diagnose

Your undertone, value, and chroma map onto the twelve-season grid. The result comes with the reasoning: warmth cues, contrast, the tie-breakers.

04

Audit

Optional: photograph the tees you already own. We tell you which are pulling their weight and which are quietly working against you.

Plate 02 — Artifact STILL LIFE · 14:22
prompt: still life, a Pantone-style swatch book opened to a spread of earth tones on a linen-covered desk, a small stack of folded tees to one side, brass loupe resting on the page. Shallow depth of field, 35mm, editorial stillness, no hands, no screens, no brand marks.

§ 02 / Seasons

One of these
is yours.

The old system splits the calendar into four seasons. The newly refined system gives each season three sub-seasons, denoted by Bright, Light, Dark, and Soft.

§ 04 / A note on method

Directional,
not definitive.

Phone photographs are imperfect sensors. Light shifts between frames. Skin reads differently at 9 a.m. than at 6 p.m. The model corrects for this — white-balancing against a reference chart, sampling across images, weighing hair and eye against lip and iris. But the result you receive is directional, not definitive.

The twelve-season system is a useful tool. Your palette is a starting point, not a decree. Wear what you want; the catalog is here to make the starting point easier to find.
