Tool usage guide
The LCH to HSL Converter is a precise utility designed to translate perceptually uniform LCH color values into the HSL format, ensuring your colors are compatible with standard web development and screen display requirements.
Background
The design team provided a brand color palette in LCH format, but the existing codebase relies on HSL for all CSS variables.
Problem
Need to convert the primary brand color 'lch(50, 50, 180)' into a valid CSS HSL string.
How to use
Input 'lch(50, 50, 180)' into the LCH Input field and select 'css' as the Output Format.
format: cssOutcome
The tool outputs 'hsl(180, 100%, 50%)', which can be directly pasted into the CSS file.
Background
A set of UI tokens was exported from a design tool in LCH format, and they need to be converted into a simple comma-separated list for a custom script.
Problem
Manually converting dozens of color values is prone to error.
How to use
Paste the list of LCH values into the input area and select 'values' as the Output Format.
LCH is a perceptually uniform color space based on human vision, while HSL is a cylindrical representation of RGB, which is easier for computers but less accurate to human perception.
Yes, you can input multiple LCH values separated by new lines to convert them in a single batch.
The tool accepts standard LCH input formats and outputs them into HSL, which is widely supported across all modern browsers.
You might need to convert to HSL if your current project or CSS framework does not yet support the LCH color function.
The tool uses standard mathematical transformations to map LCH coordinates to the HSL color space.
