Gpick vs Paletto Studio

Gpick is a free, open-source color picker and palette editor for Linux. It samples colors from the desktop, with magnification and keyboard control of the pointer, and can assign names to colors automatically. Palette tools let users build palettes from images, generate schemes, mix colors, adjust lightness or saturation, and create harmonious colors. For noisy or patterned sources, oversampling averages multiple pixel values using five falloff types. Gpick imports and exports Inkscape/GIMP palettes and Adobe Swatch Exchange files; export options also include MTL, CSS, HTML, and customizable text files. HTML exports can be shared as palette previews with people who do not use palette software. A floating mode provides a pointer-following window and notification-area icon for basic picking, but excludes palette editing and color adjustment. Command-line arguments let other programs and scripts use Gpick. Downloads include Debian and Ubuntu packages for amd64 and source archives. The project repository identifies its license as BSD-3-Clause.

Paletto Studio is a free web-based color tool for surface pattern designers. It can extract colors from a photo, refine them with harmony tools, and preview them on a design in the browser. Users can also create palettes from pasted hex codes or colors in their library. The palette tool accepts PNG, JPG, and WEBP images up to 50MB. Recoloring can start from hex codes, a library palette, or a newly created one, and palettes can be exported for Photoshop, Procreate, and more. Palette and recolor tools work without an account. Signing in lets users save palettes, organize them into collections, and load them into the tools. Uploaded images are processed in the browser and are not sent to Paletto Studio’s servers or third parties. Users own their designs and palettes, but the terms do not guarantee that exported colors will match physical print output; monitor calibration and substrate variation can affect it.
