How it Works

01Pick a Mode

Choose Random for instant inspiration, Base Color to build a harmony from one seed color, or From Image to extract a palette from any photo.

02Set Harmony Type

Select Analogous (smooth transitions), Complementary (high contrast), Triadic (vibrant balance), Tetradic (rich variety), or Monochromatic (tonal depth).

03Adjust Palette Size

Choose 3 to 6 swatches. Fewer colors suit minimal UIs; 5–6-color palettes work for full design systems with primary, secondary, neutral, and accent roles.

04Copy & Export

Click any swatch to copy the hex code instantly. Lock individual colors you love and regenerate the rest until the entire palette is perfect.

What is a Color Palette Generator?

Color Palette Generator tool interface with upload form on toolsace.io
Great design starts with a great color palette, but choosing colors that work harmoniously together is harder than it looks. Our Color Palette Generator takes the guesswork out of color selection by instantly creating beautiful, balanced palettes based on established color theory principles. Whether you need a complementary pair, an analogous trio, a triadic scheme, or a monochromatic range, the generator produces professional-grade palettes with a single click.

Designers and developers use it to kickstart brand identity work, UI design, website themes, and illustration projects. The tool generates palettes in multiple formats — HEX, RGB, and HSL — so you can copy values directly into CSS, design software like Figma or Adobe XD, or any other creative workflow. Each color in the palette is displayed with its exact code, making it easy to implement without any color conversion steps.

Beyond random generation, you can lock in colors you love and regenerate the rest of the palette around them — a powerful feature when you need to match an existing brand color or a specific design requirement. The result is a tool that feels both intuitive and professionally capable. Completely free, no account needed, and works on any device.
