Colour Memory — The Evidence Layer for Colour

# Colour Memory > Cultural colour intelligence API and MCP server. Named, evidence-graded historical colours across dozens of original-research archives, served to AI agents, designers, and developers. Every result is provenance-labelled: documented fact, inferred value, and interpretation are always kept separate. Deterministic colour science (CIEDE2000, WCAG contrast, Lab/LCh) alongside primary-sourced cultural, historical, and material context. Not licensed data, not scraped, not LLM-generated. Colour Memory exists because RGB and hex are pixel formats, not a knowledge layer. A hex code cannot tell you that a colour was once punishable by law to wear, that it reads as mourning in one culture and celebration in another, or that mixing two pigments together was recorded as dangerous four hundred years ago. Colour Memory answers those questions from original archive research, with every claim traceable to a source. ## For AI agents and developers - MCP server: https://api.colourmemory.com/mcp — connect any MCP-compatible agent (Claude, Gemini, etc.) for instant access to the full toolset - REST API and getting started: https://www.colourmemory.com/docs.html - Live archive browser: https://www.colourmemory.com/archive.html - Pricing: https://www.colourmemory.com/pricing.html ## Core tools - query_hex — match any hex value to the nearest historically documented archive colour, with cultural provenance and CIEDE2000 distance - query_conceptual — search the archive by concept, mood, or culture - colour_name_generator — generate archive-verified, provenance-cited product colour names - cultural_risk_assessment — score a hex or palette for cultural sensitivity across global markets - palette_verdict / palette_iterate / palette_compare / palette_export — palette scoring, natural-language refinement, comparison, and export to CSS/Figma/Tailwind - accessibility_check / accessibility_matrix — WCAG 2.1 AA/AAA contrast and compliance - simulate_colour_blindn
