01 · About

Not a palette tool.
A field instrument.

01 · Read

Photographs become records.

Pigments, weather, hour and mood — read into a structured plate, the way a librarian catalogues an image.

02 · Keep

An archive that doesn't leave.

Every reading stored locally. No accounts, no upload, no cloud — your atlas lives only on your device.

03 · Send

Editorial cards, only on demand.

Export PNG, PDF or JSON when you choose. Nothing leaves until you decide it should.

02 · For whom

keep images like field notes.

03 · How it works

Four movements.
One quiet ritual.

01

Import or shoot

Pull from camera roll or take a frame. The instrument never asks for more than a single photograph.

02

Read pigments

Six core colours are extracted on-device. Hex, role, dominance — laid out like type on a galley.

03

Name the weather

A fixed vocabulary of mood, hour and weather names the photograph without inventing it.

04

Archive or export

Keep it in your atlas, or print an editorial card — PNG, PDF, JSON — when, and only when, you wish.

An atlas of colour, built like a notebook and kept like a secret.

05 · Inside a reading

Anatomy of one plate.

HA-024

Tokyo, after the rain.

  1. 01 · ID

    A serial, like a page.

    Every reading is numbered HA-###. The atlas reads like a periodical, not a feed.

  2. 02 · Cores

    Six pigments, ranked.

    Six dominant colours extracted on-device, with HEX values and proportional weight.

  3. 03 · Weather

    A named condition.

    From a fixed vocabulary: after-rain, fog through, low cloud, dry sun. The photograph's atmosphere, not your guess.

  4. 04 · Title

    An italic caption.

    A short editorial title — yours to write, or auto-suggested from the place and the weather.

  5. 05 · Coda

    Mood, hour, weight.

    The metadata strip: a mood word, an hour band, the proportional bar. The footer of a printed page.

06 · Specifications

A short, honest tech sheet.

09 · FAQ

A few likely questions.

Q · 01

Does HueAtlas upload my photographs?

No. Readings happen on device. Nothing about the photograph is transmitted, stored remotely, or seen by anyone but you.

Q · 02

How are mood labels generated?

A fixed vocabulary and local heuristics. No network LLM, no live model call — every name comes from the same compact, on-device library. The full set is published at /lexicon.

Q · 03

Can I export palettes?

Yes — HEX, JSON, PNG cards and PDF records. Everything you build is yours to send, print, or keep entirely private.

Q · 04

Is there a subscription?

No. HueAtlas is a one-time purchase. There is no recurring charge, no pro tier, no upsell.

Q · 05

iPad or Mac?

Not yet. HueAtlas is iPhone-first, designed for the device you carry into the weather.
