Palette Generator
Generate complementary, analogous, and triadic palettes from a base HEX.
Palette Generator builds complementary, analogous, triadic, tetradic, and monochromatic HEX sets from a base color for moodboards and design systems—fully local.
How it works
Enter a base HEX. The tool rotates hue and varies lightness to produce related swatches you can copy as a list.

Frequently asked questions
- Which harmonies are included?
- Complementary, analogous, triadic, tetradic, and monochromatic scales.
- Does it upload my brand color?
- No. Generation runs locally from the HEX you enter.
- How is monochromatic built?
- The tool keeps hue/saturation and steps lightness toward darker and lighter tones.

- Copy the HEX list and map roles in your token file or theme.
- Will results match Photoshop?
- Hue math follows standard HSL rotation; creative tools may use other color spaces.
