Free Colour Palette Generator, Build Beautiful Brand Palettes Instantly

Choosing the right colour palette is one of the most consequential decisions in any design project. Colours communicate brand personality, set emotional tone, guide the user's eye, and signal interactivity. Get them right and your product feels considered and trustworthy. Get them wrong and even great content struggles to land. Our free Colour Palette Generator was built to make that decision faster, smarter, and more enjoyable, whether you're designing a landing page, refining a brand, or building a full design system.

The generator produces harmonious palettes of three to twelve colours using proven colour-theory algorithms, complementary, analogous, triadic, tetradic, monochromatic, and split-complementary schemes. Hit randomise to roll a fresh palette, lock the swatches you love, and keep generating until every colour earns its place. Lightness and saturation sliders let you tune the whole palette in real time, with locked swatches preserved exactly so your protected colours never drift. A Reset all button restores everything to defaults in one click.

Need to start from a real-world reference? Drop any image into the extractor or paste a URL, and the tool runs a client-side dominant-colour extraction (median-cut with k-means refinement) to pull a palette straight out of the picture. The image is never uploaded, all processing happens in your browser. You can pull a full palette or just a base colour to seed harmony generation around it.

Five preview layouts cover every scenario: Cards for spec sheets, Landscape and Portrait for brand decks, Circles for moodboards, Strip for social headers, and the new Shades layout, which expands each swatch into a row of stepped tints and shades from -50% to +50% lightness in 10% steps. Click any cell to copy that exact variation, perfect for building hover states, disabled states, and full tonal scales without leaving the tool.

Each palette is exportable in the formats designers and developers actually need. Copy individual swatches as HEX, RGB, or HSL with a single click. Export the full palette as CSS custom properties, Tailwind config snippets, SCSS variables, or as PNG, JPEG, WebP, or SVG at preset sizes for social, story, banner, wide, and print. New ZIP downloads bundle every layout in one file or every lifestyle preview scene in another, ideal for handing off a complete asset pack to a client.

The locking model is intentional and consistent: a locked swatch is protected from regeneration, from lightness and saturation tuning, and from being dropped when you reduce the colour count. Manual edits still work, type a new hex into a locked card and it updates. This makes it safe to lock a brand colour and explore variations around it without ever losing your anchor.

Beyond random generation, the tool includes a community gallery where you can browse, search, like, and publish palettes shared by other users. Find a palette you love and apply it in one click, the generator highlights the source so you always know where the inspiration came from. The Share link button copies a URL that opens the exact palette, tuning, layout, and preview scene anywhere, perfect for sending picks to a client or teammate without an account.

Accessibility is baked in. Every palette displays contrast information so you can immediately see which combinations meet WCAG AA and AAA standards for body text and large text. This pairs beautifully with our Colour Contrast Checker for deeper audits. Designing inclusive products isn't optional any more, and a palette that fails contrast at the inspiration stage will fail it in production too.

A few best practices we've learned from building dozens of brand systems: start with one anchor colour that carries the most weight (usually your primary brand colour) and lock it, then build the palette around it. Use the Shades layout to derive UI states (hover, active, disabled) from each anchor instead of guessing hex codes. Limit your accent colours to one or two, more than that and the design starts to feel chaotic. Always include neutral tones, they're what make the accent colours pop. And test palettes in context, against real photography, real typography, and real UI components, before committing.

Common workflows: brand designers use the image extractor to pull palettes from mood photography in early discovery, then lock the founder's preferred hue and tune saturation until something clicks. Web developers use the Shades layout to extend a brand colour into a full UI tonal scale. Marketers use the lifestyle preview scenes and ZIP export to coordinate campaign visuals across email, social, and landing pages in one pass. Educators and students use it to learn colour theory in practice, the live preview is a far better teacher than any textbook diagram.

Because everything runs client-side, palettes are generated, extracted, and previewed instantly with no network latency. Nothing you create is uploaded unless you explicitly publish to the community gallery, and even then you control whether to share anonymously. It's the kind of tool we wished existed when we started, fast, private, free, and built for actual production use rather than just inspiration screenshots.
