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.
Key Features
- Supports RGB, HSV, OKLAB, OKLCH, CMYK, and colour-temperature representations.
- Converts a colour between the available colour spaces as the selected representation changes.
- Adds multiple colour-space panels to the same window and removes panels individually.
- Provides linear and normalised colour previews for each panel.
- Samples a colour directly from the screen.
- Copies the currently selected colour value to the clipboard.
- Offers an expanded view with editable hexadecimal values and an sRGB readout.
- Lets users enter a HEX value to update the displayed colour interactively.
- Includes optional graphical views of colour-space components.
- Provides keyboard shortcuts for toggling graphs, changing the expanded layout, and copying values.
- Includes translations, including Czech, Dutch, Portuguese, and Swedish.
- Runs offline and supports both keyboard and pointing-device control.
