ColorPalette Pro

ColorPalette Pro is a free, open-source web app for generating customizable color palettes from a base color. It offers analogous, complementary, split complementary, triadic, tetradic, and tints-and-shades palettes, with square, triangle, circle, and diamond variations for each type. Enter a color as text, adjust sliders, use the eyedropper, revisit history, choose a random color, or provide a URL. Supported color spaces include OKLCH, LAB, LCH, HSL, and RGB. UI mode creates palettes for interface design, including surface and on-surface colors, and switches between light and dark palettes with the app’s dark mode. Copy palette values as CSS, download a CSS file, create an image, or share a URL that preserves the selected color and most other options. Palette images can be dragged into Figma for sampling with its eyedropper. Color names are matched to nearby names using hex values, and the project uses Color.js for color-science functionality. The maker describes the tool as intended for interface palettes and dynamic theming. Its GitHub repository identifies the project as MIT licensed, and the maker says there are no plans to monetize it with ads, subscriptions, or other means. The eyedropper is unavailable in Firefox and mobile browsers.

ColorPalette Pro suits people creating interface palettes or dynamic themes from a chosen color, especially those who want to share palette settings or move a palette image into Figma. It is also useful for homeowners exploring color combinations, though the maker describes its intended use as interface design.

Choose ColorPalette Pro if you want to explore color relationships, export palettes, and share the settings through a URL at no cost. Its UI mode is geared toward interface palettes and themes. Look elsewhere if you need an eyedropper in Firefox or a mobile browser.

ColorPalette Pro is a free web app for generating palettes from a starting color. It is best suited to interface designers and developers shaping themes, rather than homeowners choosing paint for a room or coating. Its flexible color exploration and export options are useful, but its interface-design focus and browser-limited eyedropper make it a poor fit for surface-color selection.

Overview

Enter a color and generate analogous, complementary, split-complementary, triadic, tetradic, or tint-and-shade palettes. Each method offers square, triangle, circle, and diamond variations, giving users multiple ways to explore a color relationship. Support for OKLCH, LAB, LCH, HSL, and RGB is a meaningful advantage for people who want to work in a particular color space rather than rely on a single model.

The app is designed around interface palettes and dynamic theming, not paint matching. Its UI mode creates interface-oriented palettes with surface and on-surface colors and switches between light and dark palettes. There are no accessibility checks, so it is a palette-generation tool, not a complete workflow for validating an interface. For homeowners, it can help explore color relationships, but it does not provide image extraction or a paint-specific selection workflow.

Key features

Flexible color input and exploration

Users can enter a color as text, adjust sliders, sample with an eyedropper, revisit color history, choose a random color, or use a URL. This accommodates both a known starting color and open-ended exploration. The eyedropper is unavailable in Firefox and mobile browsers, however, which rules it out as a dependable sampling method for users on those platforms.

Exports and sharing

Palettes can be copied as CSS values, downloaded as a CSS file, or generated as an image. The image can be dragged into Figma and sampled there, while a shareable URL preserves the selected color and most other options. These are practical handoffs for interface work; CSS and Figma exports are less directly useful to someone comparing paint colors for a wall or piece of furniture.

Color names and foundations

The app calls a color-name API to find the nearest name from a hex value, which can make a palette easier to discuss than a list of codes alone. Color-science functionality uses Color.js. The project is MIT licensed, and the maker says there are no plans to monetize it through ads, subscriptions, or other means. The README points users to the app’s question-mark button for its manual.

Pricing

ColorPalette Pro is free at no cost, with no ads or subscriptions planned. The free plan includes palette generation and PNG and CSS exports; there are no paid tiers to weigh against it. This makes it straightforward for individual designers and developers to try as a palette tool, though it does not add image extraction or accessibility checks for users who need those capabilities.

Platforms

ColorPalette Pro is a web app. Its eyedropper does not work in Firefox or mobile browsers, so users who depend on sampling colors should use a supported browser rather than expect the feature to work across devices.

Who it's for

This is a strong fit for interface designers and developers who want to derive palettes from a base color, explore several color spaces, and pass results into CSS, Figma, or a shareable URL. Its UI mode is especially relevant to people building light and dark themes. It is less suited to homeowners choosing a real-world paint, stain, or coating: the app focuses on digital palettes and does not include image extraction or a paint-selection workflow.

Pros and cons

• Pros: Six palette methods and four variations per method give interface teams several directions to explore from one starting color.
• Pros: CSS, CSS-file, image, and URL sharing options support handoff to code, Figma, or another collaborator.
• Pros: The free, open-source app has no planned ads or subscriptions.
• Cons: The eyedropper is unavailable in Firefox and mobile browsers, limiting a useful way to start from an existing color.
• Cons: UI palettes are not accompanied by accessibility checks, so users must assess accessibility separately.
• Cons: There is no image extraction, and the tool is oriented toward interface theming rather than selecting paint for physical surfaces.

Alternatives

Verdict

Choose ColorPalette Pro if you build interface palettes and want a free way to generate color relationships, switch between light and dark themes, and export or share results. Look elsewhere if your main goal is choosing paint for a real surface, if you need accessibility checks, or if you rely on an eyedropper in Firefox or a mobile browser.
