Why generate a color palette
Picking colors that actually work well together is harder than it looks — random guesses often clash, and manually calculating complementary or triadic hues means understanding color theory and doing hue-wheel math by hand.
This tool applies that math for you instantly in your browser: pick a base color and a harmony type, and you get five colors that follow an established color-theory relationship.
Choosing a harmony type
| Harmony | Best for | Why it's worth checking |
|---|---|---|
| Monochromatic Safe default | Clean, cohesive UI or branding | Uses one hue at different lightness levels, so it's hard to get wrong. |
| Analogous | Calm, natural-feeling designs | Neighboring hues on the color wheel blend smoothly. |
| Complementary | High-contrast accents, calls to action | Opposite hues create strong visual contrast — use sparingly. |
| Triadic | Playful, vibrant designs | Three evenly spaced hues give variety while staying balanced. |
Color Palette Generator without uploading anything
Every color calculation — the hue-wheel math, the lightness adjustments, the random generation — runs directly in your browser using JavaScript. Nothing is sent to a server, logged, or stored.
Because there's no upload involved, there's no limit on how many palettes you can generate or how many times you regenerate.
Your colors never leave your device. Palette generation is pure client-side JavaScript, with nothing logged or stored.

Guided palettes vs. fully random
| Approach | Best for | Trade-off |
|---|---|---|
| Guided harmony (monochromatic/analogous/complementary/triadic) Good default | Branding, UI design, anything that needs to look intentional | Colors follow color-theory rules, so they reliably work together. |
| Fully random | Brainstorming, inspiration, unexpected combinations | More variety, but you'll need to eyeball whether the result actually works. |
Start with a guided harmony type for anything client-facing, and switch to random when you just want ideas to react to.
