Color Palette Harmony Generator
Generate palettes built on real color theory: complementary, analogous, triadic, and monochromatic schemes from any seed color, with codes ready to copy.
How to use the Color Palette Generator
- Choose a base color using the picker or by entering a hex value.
- Select a harmony type such as complementary or analogous.
- Review the generated palette swatches with their codes.
- Copy the set into your design tool or stylesheet.
When the Color Palette Generator is useful
- Building a UI color scheme from a single brand color.
- Exploring accent options that pair well with an existing palette.
- Learning harmony types by seeing them applied live.
- Assembling illustration palettes with cohesive relationships.
How the Color Palette Generator works
Each harmony type follows classic color-wheel geometry: complementary places the opposite hue beside your base, analogous picks neighboring hues for gentle cohesion, triadic takes three evenly spaced hues for balance, and monochromatic varies lightness and saturation within one hue. Because the relationships are mathematical, the palettes work together by construction. All generation runs locally with instant recalculation.
Limits to keep in mind
Harmony geometry starts the palette, but perceived harmony also depends on saturation and lightness tuning for your specific medium.
Frequently asked questions
Which harmony should I start with?
Complementary for bold contrast, analogous for calm cohesion, and monochromatic when you want a single-hue interface.
Can I generate from an existing brand color?
Yes, enter its hex value and build the palette around it.
What formats are the colors shown in?
Each swatch includes its code in a copy-ready form for direct use in CSS.
