Polychromatic

Polychromatic is a free, open-source RGB lighting management application for GNU/Linux that provides graphical controls for compatible Razer peripherals. Powered by OpenRazer, it supports keyboards, mice, keypads, and other supported devices. Users can configure lighting colors, brightness, and built-in hardware effects without relying on proprietary Windows software. Its effects editor allows custom static and animated lighting designs using pixel and frame-based controls. Hardware settings include mouse DPI, polling intervals, and other device-specific options. A system tray applet provides convenient access to lighting configurations and device settings. Diagnostic tools help identify connection problems and unsupported features. Polychromatic also displays firmware versions, serial numbers, and individually addressable LED information.
