Color harmonies explained
Five classic relationships from the color wheel.
| Harmony | Best for |
|---|---|
| Complementary | High-contrast accents and calls to action |
| Analogous | Calm, cohesive backgrounds and sections |
| Triadic | Playful, balanced multi-color schemes |
| Monochromatic | Minimal, single-hue interfaces |
| Shades | Building a light-to-dark scale of one color |
Turning a palette into a usable theme
- Assign roles, not just colors. Pick one for background, one for text, and one accent rather than using all of them equally.
- Check contrast. Make sure text on a background meets accessibility contrast — a monochromatic or shades palette makes this easy by giving you light and dark steps.
- Save as variables. Drop the hex codes into CSS custom properties so the whole site can shift by editing a few values.
Frequently asked
What do the harmony options mean?
They're color relationships from the color wheel. Complementary uses opposite hues for contrast; analogous uses neighbors for a calm look; triadic spreads three hues evenly; monochromatic varies one hue's lightness; and shades step a single color from light to dark.
How do I use a palette in my project?
Click any swatch to copy its hex code, or use Copy all to grab the whole set. Paste the hex values into your CSS variables, design tool, or theme config.
Is my color data sent anywhere?
No. Palettes are calculated from color math in your browser. Nothing you pick is uploaded or stored.
