ColorDesigner vs Gpick

ColorDesigner is a web and extension platform for creating color wheels, palettes, and gradients. Its listed 13 tools include a palette builder, gradient generator, color mixer, color wheel, converter, image palette extraction, image color picking, contrast checker, and color comparison. The palette builder creates tints, shades, tones, and complementary, analogous, split-complementary, triadic, and tetradic harmonies. The Free plan costs nothing and includes 12 tools, HEX export, up to five saved colors, five palettes, and one project. Pro is $37.20 a year, billed annually, excluding tax; it adds unlimited saved colors, palettes, and projects, plus export in HEX, RGB, HSL, LAB, LCH, OKLAB, and OKLCH. Subscription plans include a 14-day free trial; the one-time payment option has no trial. The Figma plugin creates tints, shades, harmonies, and stepped gradients from selected layers or local styles, but supports solid fills only. The Photoshop extension includes a color wheel, OKLCH support, harmonies, and stepped gradients with hue interpolation across color spaces.

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.
