Result schema overview

The complete JSON has five primary layers:

1. versions — corpus, protocol, metric, and runner identifiers.
2. sampleSize and checksums — scope and integrity context.
3. keyFindings, methodSummary, holdoutSummary, and distributions — derived public findings.
4. protocol — embedded assumptions needed to interpret the results.
5. results[] — normalized seed, four method records, 11 final shades, contrast evidence, and raw metric arrays.

{
  "seed": { "id": "...", "hex": "#...", "cohort": "reference" },
  "versions": { "benchmark": "1.0.0", "protocol": "...", "metrics": "...", "runner": "..." },
  "methods": [{
    "method": "oklch",
    "shades": [{ "shade": 50, "hex": "#...", "oklch": {}, "contrastOnWhite": 1.0, "contrastOnBlack": 21.0, "gamutMapped": false }],
    "metrics": { "adjacentDeltaE": [], "coefficientOfVariation": 0.0, "lightnessViolations": 0 }
  }]
}

The CSV intentionally stores one row per seed and method. Use the JSON when shade-level evidence or raw adjacent-distance arrays are required.

License and reuse

The published benchmark datasets, protocol manifest, and aggregate findings are released under Creative Commons Attribution 4.0 International. Attribute Color Pick, retain the benchmark and dataset version, and link to the permanent research page.

The downloadable source files are provided to reproduce the published evidence. Dependencies retain their own licenses. Tailwind is a trademark of Tailwind Labs; this independent benchmark is not affiliated with or endorsed by Tailwind Labs.

No proprietary Pantone values, scraped brand palette, or private user input is included.

Reproduction workflow

1. Download the engine, generator, seed corpus, protocol, and checksum file.
2. Use Node.js with TypeScript execution and install culori@4.0.2.
3. Keep the versioned CPS source available at the path documented by the generator.
4. Run the generator without changing weights or source selection.
5. Compare generated SHA-256 hashes and frozen aggregate figures.

npm install culori@4.0.2 tsx@4.23.1
node --import tsx tailwind-scale-benchmark-generator-v1.0.0.ts
sha256sum -c tailwind-scale-benchmark-checksums-v1.0.0.txt

The generator source in this release uses repository-relative imports. External reproduction may preserve that folder structure or adjust import paths without changing the engine or protocol.

Integrity hashes

Result payload:

The payload hashes describe canonical generated content before each self-referential checksum field is added. File-level hashes for the final downloadable bytes are listed in the checksum file.
