LCH to OKLCH
Color Convert Engine
Enter a color in any supported format; the engine outputs every other color space.
Input Mode
Accepts #RGB or #RRGGBB, with or without #.
Preview
#1E40AF
Preview uses the sRGB color space.
Output — all color spaces
How to use
- Enter lightness, chroma, and hue as provided by your analyzer, watch chroma limits at high lightness, then confirm hue intent against a reference gradient.
- High-chroma colors may clip when mapped to sRGB-based HEX unless your toolchain manages gamut mapping explicitly.
- Inspect both the numeric output and the rendered swatch before publishing tokens.
FAQ
What is LCH to OKLCH used for?
LCH to OKLCH is used when your source color is expressed as LCH (lightness, chroma, hue) cylindrical LAB coordinates suited to wide-gamut workflows but your destination expects OKLCH cylindrical coordinates (lightness, chroma, hue) aligned with OKLAB—common when aligning design tools, CSS, print specs, or APIs.
Is my data uploaded?
No. Processing runs locally in your browser.
Is LCH the same as CSS `lch()`?
Conceptually aligned, but verify browser support and gamut mapping when interoping with CSS Color Level 4 features.
Introduction
LCH is LAB written in cylinders—lightness, chroma (color strength), and hue—so you can adjust vividness and hue while staying in a perceptual model. That is what we treat as the from (LCH) color encoding on this page.
OKLCH expresses OKLAB as lightness, chroma, and hue—closely aligned with how CSS oklch() parametrizes modern, wide-gamut design tokens. That is the to (OKLCH) encoding you get after conversion.
A LCH to OKLCH converter bridges them when your pipeline outputs LCH but the next step expects OKLCH—without redoing the coordinate math by hand.
What is LCH to OKLCH?
LCH to OKLCH maps colors described in LCH (lightness, chroma, hue) cylindrical LAB coordinates suited to wide-gamut workflows into OKLCH cylindrical coordinates (lightness, chroma, hue) aligned with OKLAB. The perceptual aim is the same color expressed with different coordinates—ideal when downstream systems disagree on notation.
Key Features
Fast conversion helps when you are juggling LCH inputs against OKLCH consumers in the same sprint.
Live preview catches transcription mistakes early, especially when channels have different ranges or units.
Copy-ready output reduces slack-and-paste errors moving from spreadsheets or PDF specs into code.
Common Use Cases
- Shipping UI tokens where APIs expose LCH but theme files require OKLCH.
- Preparing brand palettes for mixed pipelines—web RGB alongside print CMYK or perceptual LAB QA.
- Debugging divergent pickers by exporting one canonical mix and re-importing it elsewhere.
Best Practices
- Normalize inputs (confirm units and ranges) before trusting downstream diffs.
- Compare previews on both light and dark chrome when lightness or chroma shifts affect perceived contrast.
- Bookmark the inverse OKLCH to LCH when you frequently round-trip edits.
