About this plugin

This plugin helps users create perceptually uniform colour tones, also known as colours with even perceptual contrast. Users can create multiple palettes by specifying unique Hex values and names.


Colour management

The plugin uses the OKLCH colour model to sanitise Hex code inputs and generate the Hex values for each colour variable. The variables are designed to meet specific contrast and chroma targets relative to pure white and pure black.


Specifications

If users do not provide a name for a palette, the plugin automatically detects the hue and uses it to name the palette.
