Color Palette Generator Online

Picking colors for a side project or a new brand shouldn't involve staring at a color picker and guessing what looks good. Professional designers rely on strict mathematical relationships on the color wheel to ensure harmony. This generator lets you feed it a single primary color, and it will calculate all the complementary, analogous, and triadic palettes for you.

How the Harmonies Work

Once you input your base color, the script maps it onto a 360-degree HSL color cylinder. From there, it applies precise geometric angles. For instance, a 'Complementary' color is exactly 180 degrees across the wheel, creating maximum visual contrast—perfect for making a 'Buy Now' button pop against a colored background. An 'Analogous' palette shifts the angle slightly to grab neighboring colors, which is ideal for creating smooth, modern gradients.

Triadic for Branding

If you're building a brand from scratch, the Triadic palette is often the best starting point. It grabs three colors spaced perfectly evenly (120 degrees apart) around the wheel. It gives you a vibrant, balanced scheme without the aggressive clash of pure complementary colors.

Instantly Usable

All generated palettes output directly into standard Hex codes. You can click any swatch to instantly copy the code to your clipboard and paste it straight into Figma, Tailwind, or your CSS files.
