rong is a command-line colour generator that creates Material You and Base16 palettes from visual source material.
It is aimed at desktop theming rather than simply displaying a set of extracted colours. Once a palette has been generated, configurable mappings can render the values into files used by applications and desktop components. This provides a repeatable way to make a group of programs follow the colours in a wallpaper or other source image.
This is free and open source software.
Key Features
- Extracts source colours from image files.
- Can derive palettes from video input as well as static images.
- Generates Material You colour schemes using Material colour algorithms.
- Supports Base16 colour generation for software that uses the established Base16 palette structure.
- Uses configurable templates to turn generated colour values into application-specific configuration files.
- Can write output to multiple target files during a single theming operation.
- Supports desktop components and applications including terminal emulators, status bars and other customisable software.
- Can be incorporated into wallpaper-driven desktop customisation workflows.
- Provides a command-line interface suited to shell scripts and automated theme switching.
- Keeps palette generation separate from the target application’s main configuration, making generated colours easier to replace or regenerate.
- Uses Material Color Utilities for Material palette generation.
