ColorPalette Pro review
A flexible open-source palette generator with advanced color-space and export controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ColorPalette Pro is a browser-based color palette synthesizer for designers, developers, and artists who want control over how palettes are generated. It creates analogous, complementary, split-complementary, triadic, tetradic, and tints-and-shades palettes from a base color. Users can choose square, triangle, circle, or diamond generation styles, work in multiple color representations, and switch between palette and UI generation modes. Its open-source model also suits users who prefer inspectable software and repository-based distribution.
The standout strength is the depth of its color mechanics. ColorPalette Pro accepts text color input and screen sampling with an eyedropper, then adds sliders and waveform-based effect controls for further adjustments. Support for OKLCH, LCH, OKLAB, LAB, P3, HSL, RGB, and HEX gives developers and designers several ways to define and refine colors. A history of up to 240 previous selections helps users revisit recent choices, while shareable URLs preserve palette settings for collaboration or reference.
Export and sharing are practical additions: palettes can be downloaded as PNG images or CSS files, and palette CSS can be copied directly to the clipboard. The product is less suitable for workflows that depend on accessibility validation, extracting colors from images, integrations, brand libraries, or print color management. Users seeking advanced palette construction in an open-source web tool should consider ColorPalette Pro; teams requiring broader workflow coverage should choose a product that includes those capabilities.
