How to use Color Palette Generator
- 1
Pick a base color — drag the native color picker or paste a HEX string into the field.
- 2
Five palettes regenerate live: complementary (180 degrees opposite), analogous (neighbouring hues), triadic (120 degrees apart), tetradic (90 degrees apart), and monochromatic (single hue, varied lightness).
- 3
Copy individual colors with the inline Copy button or grab a whole palette as CSS custom properties.
- 4
Iterate by picking a new base — the palettes update on every change, so you can scrub through hue space.

| Tool | Main limitation |
|---|---|
| Adobe Color | Requires Adobe sign-in to save palettes |
| Coolors.co | Excellent free tier but limited harmony selection without upgrading |
| Manually rotating HSL | Easy to fumble the math and end up with off-axis hues |
| Color Palette Generator | Free, runs in your browser, no sign-up, no watermarks, no file-size limits beyond your device memory. |
Limitations & things to know
- Lightness and saturation steps are not user-configurable in this release
- Monochromatic palette uses fixed lightness offsets — extreme base colors may produce flat-looking sets
- No accessibility contrast checking between palette colors
About Color Palette Generator
Color harmony is the difference between a palette that feels intentional and one that feels random. The classic harmonies — complementary, analogous, triadic, tetradic, and monochromatic — were codified centuries ago and remain the backbone of modern brand and UI palettes. Xevon Tools' Color Palette Generator implements all five from a single base color, computed correctly in HSL hue space. That detail matters: a lot of cheap palette generators rotate in RGB, which produces mathematically related but visually wrong harmonies. Working in HSL means a complementary pair on our tool sits exactly opposite on the perceptual color wheel, and an analogous palette walks 30-degree steps the way a designer would expect. The output for each harmony is a 5-color set tuned to give you a usable brand palette — typically a primary, two supporting tones, and two background/surface colors. Click the Copy CSS vars button to drop the whole palette into your design system as :root custom properties; the slug names match the harmony so you can keep multiple palettes in scope while you decide which to ship. Live regeneration as you change the base means iteration is instant, which is critical when you're scrubbing through hue space looking for the brand color that 'feels right'. Everything runs locally — no signup, no rate limit, no logging of which palettes you build — making the tool safe for confidential brand work and competitive launches.
