## Tools (91)

- `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).
- `colour_timeline`: Given a concept or colour name, traces its documented appearances across cultures and centuries in chronological order.
- `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).
- `design_session`: One-call compound tool. Submit a concept, medium, audience, and constraints — receive a complete design package: historically grounded palette, cultural narrative, commercial paint…
- `image_personal`: Upload a portrait photo and receive a full personal colour analysis. Determines your seasonal type (Spring, Summer, Autumn, or Winter), colour depth (light, medium, or deep), and u…
- `style_match`: The colour question every stylist gets asked: does this bag go with this outfit? Submit your outfit items as hex values with labels (dress, bag, shoes, coat, belt, scarf, etc.) and…
- `interior_specify`: Generate a complete interior colour specification from a concept or brief.
- `house_specify`: Generate a complete multi-room house colour scheme from a single archive. Where the retrieved evidence supports it, rooms are grouped by documented provenance (same object, same pa…
- `palette_generate`: Send a palette of up to 12 slots, locking some with hex values and leaving others empty.
- `palette_gradient`: Generate a perceptually smooth gradient between 2-5 archive anchor colours. Each interpolated stop snaps to the nearest real archive colour by CIEDE2000.
- `palette_translate`: Map any list of hex values into a target archive using CIEDE2000 nearest-neighbour matching.
- `archive_cliche`: Find the most surprising archive colour for a concept and generate a memorable one-liner subverting the obvious expectation. Supply a concept (e.g.
