UI Colors is a free online tool that generates custom color scales and palettes quickly and easily. With just a few clicks, you can create color schemes optimized for use in user interface and web design projects.

The main features of the tool include:

Generating colors from a hex code — Enter any hex color value, and the tool will automatically generate a scale of 9 additional colors that complement the original.

Random color button — For a completely random starting point, click the “Random HEX” button to generate a random hex code to base the scale.

HSL sliders — Alternatively, manually adjust the hue, saturation, and lightness sliders to customize a color from scratch.

Export options—Once you have a palette you like, you can export it as a hex code list or save it on the site for later access. You can also share directly to Figma or Tailwind CSS format.
