Pywal is an image-based theme engine and dynamic color scheme generator that extracts dominant colors from images to create coordinated system-wide color palettes. It functions as a cross-application theme synchronizer and terminal color palette manager, updating interface colors and environment configurations in real-time.
The system synchronizes generated palettes across third-party software, window managers, and supported hardware, including RGB backlight controllers for keyboards and laptops. It integrates wallpaper management by applying a source image as the system background while simultaneously extracting its color palette.
Capabilities include template-driven configuration for exporting colors to specific applications, developer format exports in JSON and CSS, and the execution of post-processing scripts for custom setup tasks. The tool also supports theme library management, color mode switching between light and dark schemes, and the restoration of previously used palettes.
