Color Palette Generator AI vs Gpick

Color Palette Generator AI creates 13-color brand systems from text prompts and extracts dominant colors from images such as photos, logos, screenshots and product images. Image extraction uses k-means clustering. Users can lock selected colors, change hex values and regenerate the rest of a palette around those choices. The tool checks text and background combinations against WCAG 2.1 AA and automatically corrects failing pairs. Export options include CSS custom properties, Tailwind configuration, W3C design tokens JSON and shadcn/ui themes. Ready-made configurations are available for Claude Code, Cursor, Codex and generic coding agents. Saved palettes receive permanent links with preview images and can be remixed. The free API supports generation, image extraction and programmatic palette retrieval. The Free plan is free and includes unlimited generations, every export format, shareable links and API access, with no account required. Accepted image formats are JPEG, PNG, WebP, GIF and SVG up to 5MB; at least three extracted colors are needed to make a system. Uploaded images are processed for extraction and not kept, while saved palettes are stored.

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.
