OPEN COLOUR IDENTITY WORKFLOW

Find colour.
Understand colour.
Keep its identity.

A browser-ready edition of ATLAS Clarus Connect. No installation, server, account or network connection is required.

PKL FULL REFERENCEIdentity first. Production feasibility later. Device values third. Measured QC last.

Image Picker

RGB-ONLY IDENTITY BINDING · MASTER 8283ab91…747c4

Upload an image, choose a single pixel or a predefined square sample area, then click with the loupe. The observed 8-bit sRGB value is bound deterministically to the nearest ATLAS master reference. No Lab or ΔE is used for the primary assignment.

Your first palette · four steps

Choose an image and click a pixel or a sample area.
Open in Hover to inspect the reference. The Wheel is optional.
Add to palette, then give your palette a name.
Export Clarus JSON to keep a backup. Import it to restore the same references. Use ASE or GPL when taking swatches into a design app.

Continue to production: choose Prepare for print to carry the same references into two independent paths: 4C and ECG. Attach output profiles and export the handoff for local prepress.

Browser storage is local, not a backup. Clearing browser data or moving the HTML file may make saved palettes unavailable.

No measurement is bound. The selected identity remains the immutable target.

PREPARATION · OUTPUT CALCULATION OPEN

One frozen reference set. Two independent production paths. Prepare 4C and ECG side by side, each with its own output profile and print settings.

Computational ICC image previews: browser sRGB → the selected output profile → sRGB. Both paths use the same original image. Return to sRGB is relative colorimetric, with no paper-white simulation. These are screen previews, not measured print results. The source image and previews are not stored in Print JSON; save the image comparisons separately. ATLAS reference identities are unchanged.

Both paths start from the same ATLAS references. Neither path receives the other path’s device values. Profile changes preserve the source identity.

Keep the handoff as a JSON file; this preparation is held in memory only. Attached ICC files (up to 16 MiB each) are embedded in the JSON. Reference device values, PDF/X output and physical measurement remain separate steps. The readable report is a preparation record, not a colour proof.

About this bundle

READY_PENDING_VISUAL_AUDIT

Identity baseline

13,283 master references. Zero-based atlas_row_id. Deterministic RGB-only reference binding. Workflow v3.4.0.

Local by design

This edition runs from index.html. It sends no analytics, user actions or colour selections anywhere.

Claim boundary

A displayed or simulated colour is not a physical measurement, production approval, print proof or certification.

Frequently asked questions

IDENTITY FIRST

What is ATLAS Clarus?

An open workflow for finding, understanding, collecting and handing over colour-reference identities without silently redefining their source.

How do I build a palette?

Choose a colour in Hover and select Add to palette. You can create, name, duplicate, sort, import and delete several local palettes. The active palette is shared by Hover and Wheel.

Which exports are included?

ASE for Adobe/Affinity, GPL for GIMP/Inkscape, Figma-compatible Tokens JSON, CSS custom properties and Clarus JSON with identity evidence.

Does an export preserve the identity?

Clarus JSON retains the full reference metadata. Other application formats carry usable names and exact master RGB, but their host applications may not retain every provenance field.

Is the displayed colour physically exact?

No. Screen colour depends on display, profile and viewing conditions. It is a reference representation, not a measured print, textile, coating or production approval.

Does the bundle track users?

No. It runs locally, sends no analytics or colour selections, and stores the shared palette only in this browser's local storage.

What does frozen A′ v0.4 mean?

The established selection and ranking logic is not changed by this browser edition. Interaction Wheel v0.5 adds descriptive diagnostics only.

Is this a Pantone library?

No. Observed source-context views are descriptive and claim no Pantone identity or equivalence. ATLAS references remain independently addressed.

Colour boundary

Reference identity is not physical colour certification. Screen simulations, exports and application values do not constitute a measured production result.
