Guide

How to use the color palette generator

Use this color palette generator to create palettes for websites, dashboards, landing pages, brand concepts, design systems, and UI mockups. Generate random palettes, lock colors you like, extract colors from an image, check adjacent contrast, and export the result as HEX, CSS variables, Tailwind colors, or JSON.

  1. 1

    Generate a palette

    Click Generate to create a fresh color palette. Choose between 3 and 7 colors depending on how many design tokens you need.

  2. 2

    Lock useful colors

    Lock any color you want to keep, then generate again to replace only the unlocked colors.

  3. 3

    Start from a mood or image

    Load a curated mood preset or upload an image to extract a palette from its dominant colors.

  4. 4

    Export the palette

    Copy HEX values, CSS variables, Tailwind color config, JSON, or a share link for the palette.

Common color palette mistakes

  • Using too many saturated colors without neutral tones for backgrounds and surfaces.
  • Choosing colors that look good together but fail contrast for text and interface states.
  • Forgetting to assign roles such as primary, secondary, accent, neutral, and highlight.
  • Exporting raw colors without consistent names for CSS variables or design tokens.
  • Relying on random palettes without checking how colors work in real UI components.

Frequently asked questions

Can I lock colors while generating a palette?

Yes. Lock any color you want to keep, then generate again to update only the unlocked colors.

Can I extract a palette from an image?

Yes. Upload an image and Toolix will sample dominant colors in your browser to create a matching palette.

What export formats are supported?

The palette generator exports HEX values, CSS variables, Tailwind color config, and JSON.

Are uploaded images sent to a server?

No. Image sampling and palette generation run locally in your browser, so uploaded images stay on your device.
