Color Palette Generator AI

Overview

The tool creates complete 13-colour brand systems from text prompts, or builds a palette around colors extracted from a photo, logo, screenshot or product image. That combination supports both early exploration and work that starts with an existing visual reference. Image uploads must be JPEG, PNG, WebP, GIF or SVG, no larger than 5MB, and yield at least three extracted colors for a system to be generated.

Once a palette is created, you can lock selected colors, edit their hex values and regenerate the rest around them. That is useful when one brand color is fixed but the supporting system is still open to revision. Saved palettes get permanent links with preview images and can be remixed later. Uploaded images are processed for extraction and not kept; only palettes you explicitly save are stored. Generated palettes may be used commercially without attribution.

Key features

Accessibility and exports

Color Palette Generator AI checks text and background pairings against WCAG 2.1 AA and automatically corrects combinations that fail. This helps catch contrast problems while shaping an interface palette, but it is not a substitute for reviewing accessibility across a finished product.

Exports include CSS custom properties, Tailwind configuration, W3C design tokens JSON and shadcn/ui themes. Ready-made configurations for Claude Code, Cursor, Codex and generic coding agents add a direct route into coding workflows. These options make the product more useful to developers than a palette tool that stops at visual previews.

Image extraction and API

Dominant image colors are extracted using k-means clustering, making an existing image a practical starting point for a system rather than just a source of inspiration. The free API supports palette generation, image color extraction and programmatic retrieval of brand palettes, so it can suit developers who want to incorporate palette work into software workflows.

Pricing

The Free plan costs 0.00 USD per free and includes unlimited generations, every export format, shareable links and API access, with no account required. There is no need to pay or sign up to try the core workflow, and the plan's unlimited generations avoid a quota trade-off for ongoing use. For a solo designer or developer, it covers the listed capabilities without a paid tier to unlock them.

The free plan is the only plan given, so there is no higher tier to compare for additional capacity or team use. The privacy policy identifies Anthropic Claude as the primary palette-generation model and OpenAI as the fallback; Supabase, PostHog and Vercel are also used.

Platforms

Color Palette Generator AI is available on the web and through an API.

Who it's for

Designers who need prompt- or image-led palette exploration, and developers who want accessible color systems in familiar export formats, are the clearest audience. The API, agent configurations and commercial-use permission also suit product work. It is a less natural choice for people looking for paint-product matching or a mobile app.

Pros and cons

• Pro: Unlimited free generation, API access and all export formats mean the free plan supports both exploration and implementation without an account.
• Pro: Locking and editing colors preserves chosen brand anchors while the rest of the system changes.
• Pro: WCAG 2.1 AA checks and automatic corrections address contrast during palette creation.
• Con: Image-based generation depends on an upload meeting the 5MB limit and yielding at least three extractable colors.
• Con: Its exports and coding-agent configurations are focused on digital design, not paint selection or specifications.

Alternatives

Verdict

Choose Color Palette Generator AI if you need a digital brand palette that can be generated, refined, checked for contrast and exported into a development workflow without paying or creating an account. Its combination of an unlimited free plan, API and practical implementation formats is the main reason to choose it. Look elsewhere if your priority is a physical color catalogue, mobile access or matching a palette to paint products.
