A Color Palette Generator builds a cohesive set of colors from a single seed color, using the mathematics of color harmony. Instead of guessing which colors "go together," you pick one color you love β your brand color, a photo's dominant tone, a shade from a design you admire β and the tool produces a balanced five-color palette based on proven relationships on the color wheel. The result is a set of swatches that look intentional rather than random, ready to drop into a website, app, presentation, or brand guide.
The generator supports the classic harmony modes designers actually use. Analogous palettes take colors next to each other on the wheel for a calm, unified feel. Complementary pairs colors opposite each other for maximum energy and pop β think call-to-action buttons. Triadic uses three evenly spaced hues for a vibrant but balanced look, while tetradic (two complementary pairs) gives rich, complex schemes for larger designs. Monochromatic and shades/tints modes build depth from a single hue, perfect for minimalist layouts and dark-mode themes where you need many steps of one color.
Everything is generated and copied entirely in your browser. No account, no upload, no "premium palettes" locked behind a paywall β click a swatch to copy its hex code, lock the colors you like while re-rolling the rest, and export the finished palette as CSS variables for your stylesheet. It is the fastest path from one good color to a complete, working scheme.
From a single color to a full palette in under a minute:

The color wheel is the map, and harmony modes are the routes. Colors that sit adjacent on the wheel share undertones, so analogous palettes feel serene and natural β ideal for wellness, food, and editorial brands. Opposites intensify each other: a blue button on an orange background vibrates with energy, which is why complementary pairs dominate sports and entertainment. Equally spaced triads and tetrads distribute visual weight evenly, giving playful brands richness without chaos.
Value and saturation matter as much as hue. Two colors can share a wheel relationship and still clash if one is neon and the other is pastel. The shades/tints mode solves this by keeping hue constant and varying only lightness β the technique behind most professional dark-mode themes. A practical rule of thumb: give roughly 60% of your design to the dominant color, 30% to a supporting one, and 10% to a bold accent. Your palette generator gives you the ingredients; the 60-30-10 rule tells you how to plate them.
Web and UI designers mocking up new layouts, developers who need a decent palette without a design background, brand owners refreshing an identity, bloggers and creators styling their sites, presentation makers tired of default themes, and students learning color theory by experimenting. Anyone who has stared at a blank stylesheet wondering "what colors?" will finish faster with this tool.
Five is the sweet spot for most sites: a background, a surface, a text color, a primary brand color, and an accent. Our generator outputs exactly five swatches to match this pattern.
Triadic picks three colors evenly spaced around the wheel (120 degrees apart) β vibrant but manageable. Tetradic picks two complementary pairs β richer, but it takes more discipline to keep balanced. Start with triadic if you are unsure.
Yes. Colors cannot be copyrighted, and every palette this tool generates is free to use in personal and commercial projects with no attribution required.
Use the Export CSS variables button, paste the block at the top of your stylesheet, and reference the variables (var(--color-1) and so on) wherever you need a color.
Yes β pickers, swatches, locks, and copy buttons are all touch-friendly, and the layout adapts to small screens without horizontal scrolling.
A generated palette is a starting point, not a finished design system. The practical next step is assigning roles: pick one swatch as the page background, one as the surface for cards and panels, one for body text, one as the primary brand color for buttons and links, and reserve the boldest swatch for accents and calls to action. Write those roles down next to the hex codes β future you (and your team) will thank present you.
Then stress-test the palette against reality. Check text pairings for contrast compliance, view the scheme on a cheap monitor and a phone in sunlight, and print it in grayscale to confirm the hierarchy survives without hue. If a color only works in ideal conditions, lock the keepers and re-roll the weak ones β that is exactly what the lock feature is for. A palette that survives these checks is ready to become CSS variables and ship.
