Palette Generator

What a color palette generator does

A color palette generator turns a single base color into a set of colors that work together. Instead of guessing which hues sit well side by side, it applies established color-theory rules — the same relationships painters and designers have leaned on for centuries. Under the hood each color is found by rotating the base color's hue around the color wheel by a fixed angle while keeping its saturation and lightness, so the result feels intentional rather than random. The payoff is speed: pick one color you like, choose a rule, and get a ready-to-use scheme with copyable HEX and HSL codes in seconds.

The harmony rules explained

Each rule is a different recipe for picking angles on the wheel. Knowing what they do helps you choose the right starting point:

• Complementary — two colors directly opposite each other (180° apart). The highest-contrast pairing; great for a punchy accent against a dominant color, but tiring if used in equal amounts.
• Analogous — three colors that sit next to each other (about 30° apart). Calm, cohesive and easy on the eye, like the colors of a single sunset. Ideal for backgrounds and gentle gradients.
• Triadic — three colors evenly spaced 120° apart. Vibrant and balanced; let one lead and use the other two sparingly.
• Tetradic — four colors forming two complementary pairs. The richest scheme, but it needs a clear dominant hue or it can look busy.
• Split-complementary — a base color plus the two neighbours of its complement. Keeps much of the contrast of a complementary scheme while feeling softer and more forgiving.
• Monochromatic — a single hue walked from dark to light. Clean and minimal, and impossible to clash because every color shares the same hue.

How to build a usable palette

A harmonious set of colors is a starting point, not a finished design. The classic guideline for actually applying them is the 60-30-10 rule: let one color fill about 60% of the space (usually a light or neutral background), a second carry 30% (your main brand or surface color), and a third accent take the final 10% — buttons, links and highlights. Splitting attention this way stops two strong colors from fighting for dominance.

Almost every real interface also needs neutralsthe wheel won't hand you: a near-black for text, a near-white for backgrounds, and a few greys for borders and muted copy. Add them alongside your generated colors. Finally, sanity-check that text placed on each color is readable — a beautiful palette that fails contrast is unusable, so keep accessibility in mind from the start.

From palette to product

Once you are happy with a scheme, export it. This tool gives you CSS custom properties (--color-1, --color-2, …) you can paste into a stylesheet, and a Tailwind color block ready to drop into theme.extend.colors. Copy any single swatch as HEX, or grab the whole set at once. From there, run the key pairings through a contrast checker before you ship, and if a color earns a permanent spot in your design system, promote it to a named token so the rest of your team uses the same value.

To turn a finished scheme into a full set of semantic roles and tokens, move it into the brand kit, and always run your text-and-background pairs through the contrast checker.
