Why HSL Is Helpful for Palettes

HSL represents colors using hue (color family), saturation (intensity) and lightness (brightness). This makes it easier to generate related colors – for example, slightly lighter or darker variations of the same hue – without guessing RGB values. The tool uses HSL under the hood to generate lighter/darker shades and complementary colors.

Privacy-Friendly and Browser-Based

All calculations happen in your browser using JavaScript. No color values or palette data are sent to any server. This keeps your design experiments and client palettes private and fast.
