About Irodori

Irodori puts East Asian traditional color systems and modern perceptually uniform color spaces on the same desk. You can pull a color out of a photo, convert it to OKLCH, check it against WCAG, and read its traditional name — all without the page ever talking to a server.

Twenty-two color tools and six design-system palettes run entirely in your browser: conversion, contrast, color-vision simulation, palette generation, gradient and mesh generation, ΔE comparison, scale builders, RAL mapping and bulk conversion. Nothing is uploaded, nothing is queued, no account is required for any of it.

Sixty-six traditional colors from Japan, China, Korea and Vietnam sit alongside the modern library. Names are kept in their original script — 藍, 群青, 송화, thủy — because a translated color name is no longer the color name. Values are reviewed with cultural consultants and may still be corrected.

Contrast checking, color-vision simulation and collision audits sit next to the generators, not behind them. A palette that passes ΔE checks can still be unusable for a deuteranopic reader, so we show both numbers side by side.

Astro renders every page to static HTML at build time. The color engine is plain TypeScript running in the browser; Cloudflare Pages Functions add only the optional account, share and API endpoints. No client-side framework, no analytics, no third-party scripts or fonts.

Designers picking a palette, developers writing color tokens, accessibility reviewers checking a shipped UI, and anyone who wants to know what a traditional color actually looks like on screen.
