What is Color Scheme Creator?

Color Scheme Creator generates complete color palettes from a single base color using color theory rules. Choose monochromatic, complementary, split complementary, double split, triadic, tetradic, or analogous schemes and fine-tune each swatch. Copy a shareable link, export as CSS variables or Tailwind config, or copy hex codes.

Pick any base hex and the generator runs the standard colour-wheel rotations: 180 degrees for complementary, 150 and 210 degrees for the two split-complementary flanks, 120 degrees for triadic, 90 degrees for tetradic, and small steps on either side for analogous. Shades and tints come from the same hue with lightness shifted in fixed HSL steps, giving a clean five-stop ramp for each. Every swatch can be copied as HEX, rgb(), hsl() or oklch(), the contrast panel scores each colour against white and black for WCAG AA and AAA, and a one-click vision preview re-renders the whole palette through protanopia, deuteranopia, or tritanopia filters. Copy a share link to bookmark or hand a palette to a teammate without an account.

How to use

1. Pick a base color using the color picker or enter a hex code.
2. Select a scheme type (monochromatic, complementary, split complementary, double split, triadic, analogous, tetradic) to generate the palette.
3. Copy individual hex codes, export the full palette as CSS variables, or download as an image swatch.

When to use

• Turning a single brand hex into a full palette for a new website or app theme.
• Checking whether a logo colour has a clean complement before printing merchandise.
• Generating CSS custom properties without opening Figma or a design tool.

Result

A web developer picks their brand's primary blue (#3B82F6), generates a triadic scheme producing complementary orange and green tones, then exports the palette as CSS custom properties for their design system.

FAQ

What's the difference between triadic and tetradic schemes?

Triadic uses three colours spaced 120 degrees apart on the wheel, giving a balanced trio. Tetradic uses four colours forming a rectangle (two complementary pairs), which gives more variety but is harder to balance visually.

When should I use shades versus tints?

Shades (darker versions) work well for text, borders, and hover states on light UIs. Tints (lighter versions) are for backgrounds, disabled states, and subtle highlights. Most design systems need both ramps from the same base.

Does the generator account for accessibility contrast?

Yes — the contrast panel below the palette shows each colour's WCAG ratio against white and black with AA and AAA pass or fail badges. The 4.5:1 threshold for normal text is the one most UI work needs; switch the vision preview to protanopia, deuteranopia, or tritanopia to also see how the palette reads to people with colour vision deficiency.

Why does an analogous scheme feel calmer than a complementary one?

Analogous colours sit next to each other on the wheel, so they share a hue family and create low visual tension. Complementary colours sit opposite, which maximises contrast and feels more energetic but is harder on the eyes at large sizes.

Can I export to Tailwind config or only CSS variables?

Both are supported. CSS variables drop straight into a stylesheet under :root. The Tailwind format wraps the hex values inside a theme.extend.colors object that you can paste into tailwind.config.js.
