Color Picker for COSMIC – color utility for COSMIC desktop

Color Picker for COSMIC is a graphical colour utility developed specifically for the COSMIC desktop.

It follows the desktop’s native visual language through libcosmic and provides a focused workspace for examining colours without relying on a browser-based tool. The application is a third-party project rather than an official COSMIC component.

Its interface can accommodate several colour representations at the same time, which makes it useful when translating colours between design, graphics, and development workflows. Screen colour selection uses the desktop portal infrastructure, so the application works with modern Wayland security boundaries rather than requiring unrestricted access to the display.

This is free and open source software.
