Choosing the right colours for a data visualisation is one of the most impactful — and often most overlooked — decisions in the design process. A well-crafted palette doesn't just look good; it communicates clearly, guides the eye, and ensures your insights land with the right emphasis.

The DataMonster Colour Palette Generator uses Claude AI to generate professionally designed palettes tailored to your specific context — whether it's a corporate dashboard, a climate infographic, an F1 analytics report, or anything in between.

Simply describe your theme, choose a style and palette type, and let the AI do the heavy lifting. Lock the colours you love and regenerate the rest until your palette is exactly right.

Working with an existing brand? Upload your brand guidelines as an image and the tool will automatically extract every colour, ready to export directly into Tableau, Power BI, Flourish, or D3 — no manual transcription needed.

Every palette comes with a full suite of export formats: Tableau XML for your Preferences file, Tableau Custom Palette for the Import Swatches dialog, Power BI JSON theme files, Flourish hex lists, and D3 arrays. Plus a downloadable Markdown brief for sharing with clients or teammates.
