What the Color Palette Generator does
The Color Palette Generator takes a single base color and builds five harmonious palettes from it using established color-theory relationships: complementary, triadic, tetradic, analogous, and monochromatic. Each palette is derived by rotating the base color's hue and adjusting its lightness, so every set stays visually connected to the color you started with.
It is useful for designers, developers, and hobbyists who have one brand or accent color and need a coordinated set of supporting shades for a website, illustration, presentation, or UI. Instead of guessing which colors pair well, you get mathematically related options you can preview side by side and copy in seconds.
How to use it
Enter a base color as a 6-digit HEX value, for example #6366f1, or click the color swatch to choose one visually with your device's color picker. Both the text field and the picker stay in sync, and the palettes regenerate instantly whenever you change the base color.
Each palette appears in its own card with labeled swatches. Click any individual swatch to copy that single HEX code to your clipboard, or use "Copy all" to copy the whole palette as a JSON array of HEX strings, which is handy for pasting into design tokens or a config file. A brief "Copied!" message confirms the value was copied.
Understanding the palette types
Complementary uses the base color plus its opposite on the color wheel for strong contrast. Triadic and tetradic spread three or four colors evenly around the wheel for balanced, vibrant schemes. Analogous gathers neighboring hues for a calm, cohesive look, while monochromatic keeps the same hue and varies only lightness for a subtle, layered effect.
A good approach is to use one color as the dominant tone and the others as accents rather than in equal amounts. Analogous and monochromatic palettes tend to feel restful and are well suited to backgrounds, while complementary and triadic palettes work well when you want a clear focal point or call to action.
