HEX to LCH
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 a valid HEX color such as
#1e40afor shorthand#0af, then confirm the preview matches the color you expect. - Watch for shorthand typos, a missing
#, or pasted whitespace that silently shifts the result. - Verify the converted values wherever they will render—CSS, canvas, or design tokens.
FAQ
What is HEX to LCH used for?
HEX to LCH is used when your source color is expressed as hexadecimal notation (`#rrggbb`, often with optional shorthand) but your destination expects LCH (lightness, chroma, hue) cylindrical LAB coordinates suited to wide-gamut workflows—common when aligning design tools, CSS, print specs, or APIs.
Is my data uploaded?
No. Processing runs locally in your browser.
Does this tool support shorthand HEX values?
Yes. It supports shorthand HEX like `#0af` and full six-character values like `#00aaff` when HEX is part of the workflow.
Introduction
HEX notation encodes the red, green, and blue channels as base-16 pairs in a # string—usually #RRGGBB or the shorthand #RGB. That is what we treat as the from (HEX) color encoding on this page.
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 the to (LCH) encoding you get after conversion.
A HEX to LCH converter bridges them when your pipeline outputs HEX but the next step expects LCH—without redoing the coordinate math by hand.
What is HEX to LCH?
HEX to LCH maps colors described in hexadecimal notation (#rrggbb, often with optional shorthand) into LCH (lightness, chroma, hue) cylindrical LAB coordinates suited to wide-gamut workflows. 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 HEX inputs against LCH 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 HEX but theme files require LCH.
- 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 (expand shorthand and strip stray characters) before trusting downstream diffs.
- Compare previews on both light and dark chrome when contrast ratios matter for accessibility.
- Bookmark the inverse LCH to HEX when you frequently round-trip edits.
