Tool usage guide
The XYZ to LCH Converter is a precise utility designed to transform CIE XYZ color values into the perceptually uniform LCH (Lightness, Chroma, Hue) color space, facilitating accurate color management and design workflows.
Background
A developer is updating a website's theme to use modern CSS color functions for better accessibility and consistency.
Problem
The design system provides colors in XYZ format, but the CSS requires LCH values.
How to use
Paste the XYZ values into the input field and select 'CSS' as the output format.
format: cssOutcome
The tool outputs 'lch(50 50 180)', which can be copied directly into the CSS stylesheet.
Background
A researcher has a list of measured XYZ values from a spectrophotometer that need to be analyzed for lightness and chroma.
Problem
Manually calculating LCH for dozens of data points is inefficient and prone to error.
How to use
Paste the entire list of XYZ values into the input area and select the 'labeled' format for clear documentation.
XYZ is a device-independent color space based on human vision, while LCH is a cylindrical representation of the Lab color space, designed to be perceptually uniform.
Yes, you can paste multiple XYZ values into the input area, with each color on a new line, to process them in a single batch.
Select the 'CSS' format option to receive output formatted as 'lch(L C H)', which is compatible with modern web browsers.
Yes, the converter uses standard CIE mathematical transformations to ensure high precision in color space conversion.
No, this is a web-based utility that runs directly in your browser without requiring any installations or plugins.
format: labeledOutcome
The tool provides a clean, readable list of L:C:H values for each input, ready for inclusion in a research report.
