Color Palette Generator AI

Overview

Color Palette Generator AI is a web and API tool for creating and working with colour palettes. Its main output is a complete 13-colour brand system generated from a text prompt. For a home painting project, it can help explore combinations and extract colours from an inspiration image, but its listed exports and agent configurations are geared towards digital design and development rather than paint specifications.

You can also start with a photo, logo, screenshot or product image. The tool uses k-means clustering to identify dominant colours, then builds a system from them. Accepted formats are JPEG, PNG, WebP, GIF and SVG, with a maximum file size of 5MB. At least three colours must be extracted for a system to be generated. Uploaded images are processed for colour extraction and are not retained; only palettes you explicitly save are stored.

Generated palettes can be used for any purpose, including commercial use, without attribution. That permission applies to the palettes; it does not mean the tool identifies a matching paint product or finish.

Key features

Build and refine a palette

Prompt-based generation produces a 13-colour system. You can lock colours you want to keep, edit their hex values and regenerate the rest around them. This makes it possible to preserve a chosen anchor colour while exploring alternatives for the remaining palette.

Saved palettes have permanent links with preview images and can be remixed later. A brand colour library is also listed among the tool’s features.

Check contrast and export

The accessibility checker evaluates text and background pairings against WCAG 2.1 AA and automatically corrects pairs that fail. This is useful when a palette is intended for readable digital interfaces, though it does not assess paint coverage, durability or suitability for a particular surface.

Exports include CSS custom properties, Tailwind configuration, W3C design tokens JSON and shadcn/ui themes. Ready-made configurations are provided for Claude Code, Cursor, Codex and generic coding agents.

Use the API

The free API supports palette generation, image colour extraction and programmatic retrieval of brand palettes. That makes the tool usable both through its website and as part of a software workflow.

Pricing

The Free plan costs 0.00 USD per free. It includes unlimited generations, every export format, shareable links and API access, with no account required. The pricing model is free, and a free plan is available.

Platforms

Color Palette Generator AI is available on the web and through an API. Its support for coding agents and development-oriented export formats is aimed at digital design workflows. The stated image input options offer a way to work from visual references, but the listed features do not include paint-brand matching or named paint colours.

Who it's for

This tool is best suited to someone who wants to develop a colour direction from a prompt or an image, refine the palette and share it. Homeowners can use it to explore colours inspired by a room photo, product image or other reference, then carry that direction into paint selection. It is not presented as a paint visualizer or a catalogue of coatings, so a generated hex value should be treated as an idea to translate into an actual paint colour, not as a guaranteed product match.

It may also suit developers who need accessible interface colours, exportable design tokens or palette data through an API. Commercial use is permitted without attribution.

Pros and cons

• Pros: Free access includes unlimited generations, exports, shareable links and API use.
• Pros: Works from text prompts or images, and lets users preserve selected colours while regenerating the rest.
• Pros: Includes WCAG 2.1 AA pairing checks and automatic correction of failing combinations.
• Cons: Its exports and agent configurations focus on digital design rather than specifying house paint.
• Cons: Image-based generation requires at least three extracted colours and accepts files only up to 5MB.

Verdict

Color Palette Generator AI offers a clear route from a written prompt or image to a shareable, editable 13-colour system, with useful contrast checks and broad digital exports. Its free plan removes cost as a barrier to exploring ideas. For painting a real surface, treat the result as colour inspiration: the listed features do not provide paint-product matching, so you will still need to choose a suitable paint or coating separately.
