How It Works

A monochromatic palette keeps a single hue and only varies its lightness, from very dark to very light, producing a harmonious, professional look often used for design systems or minimalist interfaces. This tool converts your base color to HSL, fixes the hue and saturation, then automatically distributes several lightness levels between 12% and 92% to build the palette.

How does a monochromatic palette differ from a complementary palette?

A complementary palette combines opposite hues on the color wheel to create contrast, while a monochromatic palette stays with a single hue and plays only on lightness for a more restrained, cohesive result — especially suited to interfaces where color shouldn't distract from content.

How many colors should I choose for an interface?

5 to 8 shades are usually enough to cover the common needs of an interface (background, border, text, hover state, active state). Increase the number of colors if you need more granularity for complex components.

The whole palette is calculated in your browser: your base color is never transmitted to a server.
