Overview
The LAB to LCH Converter allows you to seamlessly transform CIELAB color values into the LCH (Lightness, Chroma, Hue) color space, facilitating more intuitive color manipulation and design workflows.
When to Use
- •When you need to convert device-independent LAB color data into the more human-perceptible LCH format.
- •When preparing color palettes for CSS development that requires modern LCH color syntax.
- •When you need to adjust color lightness or saturation independently while maintaining consistent hue.
How It Works
- •Input your LAB color values into the text area, using standard formats like lab(L, a, b) or simple comma-separated values.
- •Select your preferred output format, such as standard CSS syntax, raw values, or labeled LCH notation.
- •Click the convert button to instantly generate the corresponding LCH values for your design project.
Use Cases
Web designers converting legacy LAB color profiles to modern LCH CSS variables.
Graphic designers adjusting the chroma of a color without affecting its perceived lightness.
Developers standardizing color data across different design systems and software environments.
Examples
1. Converting LAB to CSS-ready LCH
Frontend Developer- Background
- A developer is migrating a design system from legacy LAB values to modern CSS LCH color functions.
- Problem
- The developer needs to quickly convert a list of LAB colors into valid CSS syntax for a stylesheet.
- How to Use
- Paste the LAB values into the input field and select 'lch(50 50 180)' from the output format dropdown.
- Example Config
-
format: css - Outcome
- The tool outputs a list of ready-to-use CSS strings like 'lch(50 50 180)' that can be copied directly into the project's CSS file.
2. Extracting Color Components for Design
UI Designer- Background
- A designer is working on a color palette and needs to understand the specific lightness and chroma values of their chosen colors.
- Problem
- The designer has LAB values but finds it difficult to adjust the 'a' and 'b' channels to change saturation.
- How to Use
- Input the LAB values and select the 'L:50 C:50 H:180°' labeled format to clearly see the individual LCH components.
- Example Config
-
format: labeled - Outcome
- The designer receives clear, labeled values that make it easy to tweak the chroma (C) while keeping the lightness (L) and hue (H) constant.

FAQ
What is the difference between LAB and LCH?
LAB uses Cartesian coordinates (L, a, b) to define color, while LCH uses polar coordinates (Lightness, Chroma, Hue), which is often more intuitive for adjusting specific color properties.
Can I convert multiple colors at once?
Yes, you can paste multiple LAB values into the input area, with each color on a new line, to convert them in a single batch.
Does this tool support CSS-ready output?
Yes, you can select the 'CSS' output format to receive values formatted specifically for use in modern web stylesheets.
Is the conversion accurate?
The tool uses standard color science formulas to ensure precise mathematical conversion between the CIELAB and CIELCH color spaces.
Do I need to install any software?
No, this is a web-based utility that runs directly in your browser without requiring any downloads or installations.
