# Palette Analyse

`POST /palette/analyse`

## Request

- Base URL: `https://api.colourmemory.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.colourmemory.com/palette/analyse`
- Auth: none declared

Match a palette of hex colours against the archive in a single call.

For each colour returns the nearest named archive entry with:
  name, archive, hex, dE2000, confidence, confidence_score,
  claim_strength (A-E), primary_source, do_not_say guardrails,
  and an alternatives array when confidence is low.

Palette-level deduplication: no two colours share the same archive entry.
Dominant colours (weight >= 0.3) get a wider internal candidate search.
Combined scoring: dE2000 penalised by record quality so weak sources
lose to good sources at similar perceptual distance.
