Color Converter
HEX ↔ RGB ↔ HSL ↔ OKLCH with picker & history.
Find the nearest CSS color name or Japanese traditional color — and search the other way too.
Closeness is ranked by perceptual colour distance (OKLab). Anything short of an exact match is only the nearest name — it will look slightly different from your input.
A tool that finds the nearest CSS or Japanese traditional color name for a given color, and can also search the other way — from name to color.
69 colors, including Akane-iro (茜色), Ai-iro (藍色), and Yamabuki-iro (山吹色) — each with kanji, hiragana reading, and romanization.
No — without the exact-match badge, it's just the closest available name, and the actual color will differ slightly. Ranking uses perceptual distance (OKLab) rather than raw RGB difference for more natural results, but it never implies an exact match.
Switch to "Name → Colour" mode and type kanji (e.g. 藍), a hiragana reading (e.g. あかね), or English (e.g. azure). Matching is substring-based.
No. All matching runs locally in your browser; nothing is sent to toco.tools servers.
