ColorPalette Pro

ColorPalette Pro is a browser-based palette generator for designers and developers shaping interface colors. It is a strong fit for exploring color relationships and moving a chosen palette into a design or CSS workflow; look elsewhere if built-in accessibility checks or dependable eyedropper support are essential.

Overview

Starting from a base color, the app generates analogous, complementary, split-complementary, triadic, tetradic, and tint-and-shade palettes. Four geometric variations—square, triangle, circle, and diamond—give each method several arrangements to compare. Support for OKLCH, LAB, LCH, HSL, and RGB makes the generator useful to people who want to work in a particular color space rather than treat color as a hex value alone.

Its clearest strength is its focus on interface palettes and dynamic themes. UI mode creates surface and on-surface colors and can switch between light and dark palettes. That provides a helpful starting point for a theme, but the app has no accessibility checks, so it cannot assess whether the resulting colors meet a contrast target.

Key features

Flexible color input and iteration

Enter a color as text, adjust sliders, pick a random color, supply a URL, revisit history, or use the eyedropper. The choice of inputs supports both deliberate work from a known brand color and open-ended exploration. The eyedropper has a practical compatibility limit: it is unavailable in Firefox and mobile browsers, making it a poor fit for workflows that depend on sampling from the screen in those environments.

Exports and handoff

Copy palette values as CSS, download a CSS file, or generate a palette image. That covers common handoffs to code and visual design, and generated images can be dragged into Figma and sampled with its eyedropper. Color changes and most other options are retained in a shareable URL, which makes it easier to pass a specific palette to a teammate. The app also uses a color-name API to find the nearest name from a hex value.

Pricing

ColorPalette Pro is free at no cost, with an open-source MIT license. The maker says there are no plans to add ads, subscriptions, or other monetization. There are no paid tiers to weigh against the free version, and the plan has no stated seat or generation quota. Its main functional omissions are image extraction and accessibility checks, so users needing either will need another tool.

Platforms

ColorPalette Pro runs on the web. The browser eyedropper is unavailable in Firefox and mobile browsers, so users on those platforms can still use the other color inputs, but should not count on eyedropper sampling.

Who it's for

Choose it if you need a free web tool for generating interface palettes from a base color, comparing several color relationships, and exporting results to CSS or Figma. It is less suitable when your process depends on extracting colors from images or verifying accessibility in the same tool.

Pros and cons

• Pros: Multiple palette methods, geometric variations, and color spaces give designers room to explore without changing tools.
• Pros: UI mode includes surface and on-surface colors for light and dark themes, making the output relevant to interface work.
• Pros: CSS exports, draggable palette images for Figma, and shareable URLs support handoff and review.
• Pros: Free and MIT-licensed, with no planned ads or subscriptions.
• Cons: No accessibility checks, so it cannot validate contrast as part of palette creation.
• Cons: No image extraction, and the eyedropper does not work in Firefox or mobile browsers.

Alternatives

Color Palette Generators is the category directory for comparing more options. Consider Pantone Connect Palette Generator if you want a free account with access to 15,000+ colors and Search, Pick, and Measure tools; its free plan also has a trial. ColorKit is another free web color-tool option, with a free account for saving colors and palettes. iWantHue is a free alternative available across web, mobile, desktop, and API platforms. Linux users can consider Gpick, a free desktop option. Color Palette Generator AI offers unlimited generations, every export format, shareable links, and an API for free without an account. For Windows, Colora is free and open source under the BSD 3-Clause license. ColorBox is a free, ad-free web and browser-extension alternative. ColorDesigner is worth considering if you want a free tier with 12 tools, limited saved colors and palettes, one project, and HEX export, or a paid Pro plan.

Verdict

ColorPalette Pro is an easy recommendation for interface designers and developers who want a free, open-source way to explore color systems and carry the result into CSS or Figma. Its interface-oriented palettes and useful handoff options are the reasons to choose it. Look elsewhere if image extraction, accessibility evaluation, or eyedropper support in Firefox and mobile browsers is central to your work.
