ZollPalette

ZollPalette is an open-source color palette framework and design system designed to help developers and designers create, manage, and apply color palettes across digital products. It provides a collection of predefined palettes and tools for generating harmonious schemes from a base color, while emphasizing perceptual uniformity and accessibility. The framework includes features for contrast assessment, color-vision accessibility checks, and automated palette validation against WCAG standards.

Users can generate palettes using harmonies such as analogous, complementary, triadic, or tetradic, and tailor them through saturation and lightness controls in a perceptually uniform color space. Outputs are available as CSS variables, JSON configuration, and swatch exports in SVG or PNG formats, easing integration with web apps, design tools, and prototyping environments. The project supports theming, localization, and integration with popular frontend frameworks through adapters and plugins.

ZollPalette originated as a community-driven project within the ZollTech ecosystem in the late 2010s and has grown through contributions from designers and developers worldwide. It is released under the MIT license and is maintained by a rotating maintainer team, with regular releases that add palettes, accessibility improvements, and tooling.

Adoption includes use by startups, agencies, and open-source projects seeking consistent branding and accessible data visualizations. The framework is praised for its modularity, clear export formats, and strong accessibility tooling, though some users note limited documentation for advanced features and occasional API changes between releases.
