What it does
Gpick samples desktop colours and builds editable palettes from them or from imported images. Its interface combines a floating picker, six comparison swatches, component sliders and a named palette list. Source code is published under the BSD 3-Clause licence.
Press Ctrl+P to open the floating picker, then collect and adjust colours in the palette. The image-palette tool adds its generated colours to the existing list, so a reference photograph can extend a set already under development.
Ordinary dragging copies colours within the list; Shift-drag moves them and Ctrl-drag replaces a destination. Dragging into an application that accepts colour drops sends only the first selected colour. Text destinations can receive the selection in the configured format, with hex codes as the default.
Save an editable palette as GPA, GPL or ASE, or export only selected colours. Export also supports MTL. The manual warns that New starts a fresh palette without prompting to save changes, so save the existing work before starting another.
