Why Use This Tool?
What is color harmony and how does this tool use it?
Color harmony refers to combinations of colors that are visually pleasing because of their relationship on the color wheel. This generator calculates real hue relationships in the HSL color space: Complementary picks hues directly opposite each other, Analogous picks hues sitting close together for a calm, cohesive feel, Triadic spaces three hues evenly around the wheel for balanced contrast, and Random Harmonious uses a golden-angle hue rotation to spread colors evenly while still feeling intentional. Every palette is computed on the fly with genuine HSL-to-HEX math, not a lookup table of preset colors.
Can I keep colors I like while generating new ones?
Yes. Click "Lock" under any swatch and it will be excluded from the next randomization, so you can iterate — regenerating only the swatches you're unsure about — until the full palette works together. This is especially useful when you've found the perfect brand accent color and just want to explore supporting shades.
Is this tool free for commercial projects?
Absolutely. Every palette generated here is free to use in logos, websites, apps, packaging, or any commercial design work, with no attribution required and no account needed. There are no watermarks, export limits, or premium tiers.
Does this tool store or upload my palettes?
No. The Color Palette Generator runs 100% client-side in your browser using JavaScript. Nothing you generate is sent to a server, logged, or stored — refresh the page and it's gone unless you've copied the codes you need. That also means it works offline once the page has loaded and never requires signup.
