• query_conceptual Ask a cultural, historical, or material colour question. Returns named archive colours with provenance and cultural context.
• extract_image_colours Extract dominant colours from a photograph using Colour Memory's proprietary k-means++ algorithm. Requires either a public imageurl, or an imageid.
• query_hex Find the closest named archive colours to a hex value using CIEDE2000 perceptual distance.
• palette_specify Generate a complete interior specification from 2-8 hex values. Returns surface assignments, 60-30-10 proportions, lighting behaviour, and archive colour names.
• colour_metrics Returns raw perceptual metrics (LRV, chroma, hue angle, warmth, undertone) for a single colour. This is one component of colourpassport.
• colour_harmonies Return complementary, triadic, analogous, and split-complementary harmonies matched to named archive colours. Also available: 'haycontrast' -- D.R.
• accessibility_check Evaluates contrast for a single foreground/background pair. For palettes or multiple colours, use accessibilitymatrix instead, it replaces multiple accessibilitycheck calls in one…
• accessibility_matrix Accept a palette array and return every foreground/background combination with contrast ratio, AA normal, AA large, AAA normal, AAA large pass/fail grades, and a summary.
• accessibility_rules Convert a palette WCAG matrix into actionable design-system rules. Returns safe pairs, AA-only pairs, large-text-only pairs, decorative-only pairs, best text colour per background,…
• colour_slugs Return every developer token format for a hex value: CSS variable, kebab-case, camelCase, PascalCase, Tailwind class, TypeScript const, SCSS variable.
• palette_light_dark Generate light-mode and dark-mode role maps from a palette. Analyses LRV, assigns background/surface/text/accent roles for each mode, checks body text contrast safety, and flags mi…
• accessibility_font Given a background hex and a palette of candidate foreground colours, return them ranked by contrast ratio with WCAG grades and specific recommendations for body text, large text,…
• archive_search Full-text keyword search across all archive colour names and notes. Find colours by name fragment, material, cultural reference, pigment type, or historical period.
• colour_combination Assess 2-5 colours as a combination for a given context (UI, data viz, fashion, interior, print, branding).
• palette_strict Like paletteconcept but with archive filtering and relevance controls. Use allowedarchives to restrict results to specific cultural traditions e.g. ['Japan'] for Japanese only.
• palette_pdf Generate a premium branded PDF specification sheet from a palette of archive entries.
• palette_audit Full palette quality audit. Scores on accessibility, cultural risk, tonal balance, colour diversity, and archive naming strength.
• brand_system Complete brand colour system in one call. Returns colour roles with archive names, light and dark mode role maps, typography guidance, usage rules per colour, design tokens (CSS, T…
• brand_asset_pack Complete brand asset pack. Returns CSS variables, Tailwind config, Figma tokens JSON, citation cards, and a Markdown brand guide. Everything a brand team needs to ship.
• accessibility_simulate Return simulated hex values for protanopia, deuteranopia, and tritanopia using the Brettel-Vienot-Mollon model.
• colour_match_paint Find the nearest named colour in commercial paint systems including Farrow and Ball and Little Greene.
• colour_card Look up a named colour and return its hex, archive, provenance, and cultural notes.
• meta_capabilities Return a live inventory of all active endpoints and MCP tools. Use this first to discover what the API can do before making calls.
• system_status Zero-argument diagnostic call: returns exactly what build is live right now (buildsha, schemaversion, schemahash, archiverevision, toolcount, generatedat, serverenvironment).
• colour_story Given a hex value, returns a rich narrative about that colour's cultural journey — where it has appeared in history, what it has meant to different civilisations, and what archive…
• palette_concept Generate a historically grounded colour palette from a cultural concept or theme. Returns 4-6 coordinated archive colours with hex values, proportions, and provenance.
• colour_mix Simulate perceptually modelled subtractive mixing of two colours in CIE Lab space (not RGB screen blending).

• image_palette Upload an image (base64 encoded) and extract its dominant colour palette, with each colour matched to its nearest named archive entry with full cultural provenance.
• colour_compare Deep perceptual and semantic comparison between any two hex values. Returns quantified differences in LRV, chroma, hue angle, warmth, and CIEDE2000 distance, plus cultural context…
• colour_cultural_risk Cultural risk assessment for a hex value or palette (symbolic weight, regional taboos, religious associations, market flags).
