Tool usage guide
The HEX to LCH Converter allows you to precisely transform hexadecimal color codes into the perceptually uniform LCH (Lightness, Chroma, Hue) color space, ensuring consistent color management across modern web and design projects.
Background
The design team provided a brand palette in HEX format, but the project requires LCH for better color interpolation in CSS transitions.
Problem
Manually calculating LCH values for a large set of brand colors is error-prone.
How to use
Paste the list of brand HEX codes into the input and select the 'lch(L C H)' output format.
Outcome
A clean list of LCH values ready to be copied directly into the project's CSS variables.
Background
A button component uses a semi-transparent HEX color (#ff000080) that needs to be converted to a solid LCH equivalent for a specific background.
Problem
The alpha channel needs to be flattened to ensure the color renders correctly on a dark interface.
How to use
Input the HEX code, select 'Composite with custom background', and set the background to match the dark UI hex value.
Outcome
An accurate LCH value that represents the final rendered color, ensuring visual consistency.
LCH is perceptually uniform, meaning it aligns better with how the human eye perceives color, making it easier to create accessible and balanced color palettes.
Yes, you can process HEX values with alpha channels and choose to composite them against a white, black, or custom background.
Yes, simply paste each HEX code on a new line in the input area to batch convert your entire palette.
The formats range from standard CSS-ready strings like 'lch(50 50 180)' to raw comma-separated values for use in programmatic applications.
The tool uses standard color space transformation algorithms to ensure high-precision conversion from sRGB (HEX) to CIELCH.
