› About this tool · FAQ

Create professional color palettes using color harmony theory, accessibility guidelines, and advanced color science. Generate complementary, analogous, triadic, and monochromatic schemes from any base color. Export to CSS, SCSS, Tailwind, and JSON.

What color harmony types are available?

Six harmony types based on color wheel relationships: monochromatic (single hue, varying lightness), analogous (adjacent hues), complementary (opposite hues), triadic (three equidistant hues), tetradic (four hues forming a rectangle), and split-complementary (base plus two colors adjacent to its complement).

How does WCAG accessibility checking work?

The tool calculates contrast ratios between generated colors and standard backgrounds (white and black). WCAG AA requires a minimum 4.5:1 ratio for normal text and 3:1 for large text. WCAG AAA requires 7:1 for normal text. Each color in your palette shows its contrast rating.

What export formats are supported?

Export to CSS custom properties (--variable syntax), SCSS variables ($variable syntax), Tailwind CSS config (tailwind.config.js format), JSON data for programmatic use, and plain text palette format. Each format is ready to paste into your project.

Can I generate a brand color palette from a single color?

Yes. Brand mode generates a complete design system from your base color: primary, secondary (30-degree hue shift), accent (complementary), light and dark backgrounds, text colors, plus semantic colors for success, warning, and error states.

How are color temperatures determined?

Colors are classified by their hue position on the color wheel. Warm colors (reds, oranges, yellows) have hues between 315-45 degrees. Cool colors (blues, greens, purples) fall between 90-270 degrees. Colors in between are classified as neutral.

What is the difference between analogous and complementary colors?

Analogous colors sit next to each other on the color wheel (e.g., blue, blue-green, green) and create harmonious, cohesive palettes. Complementary colors sit opposite each other (e.g., blue and orange) and create high-contrast, vibrant combinations ideal for drawing attention.

How do I create a Tailwind CSS color palette?

Select your base color, choose any generation mode (Brand mode works well for design systems), then set the export format to "Tailwind Config". The output is a ready-to-paste tailwind.config.js snippet with named color keys matching your palette roles.

What is a split-complementary color scheme?

A split-complementary scheme uses a base color plus the two colors adjacent to its complement on the color wheel. For example, if your base is blue, instead of using orange (the complement), you use red-orange and yellow-orange. This gives high contrast with less visual tension than a pure complementary scheme.

How many colors should a brand palette have?

A typical brand palette includes 5-9 colors: 1-2 primary colors, 1 accent, 2 neutral background shades, 1-2 text colors, and 2-3 semantic colors (success green, warning amber, error red). The Brand mode generates exactly this structure from your chosen base color.

Can I use this for data visualization color palettes?

Yes. For data visualization, use Triadic or Tetradic harmony to generate distinguishable colors, then check the accessibility ratings to ensure they work for colorblind users. Aim for colors with high contrast between each other and avoid relying solely on hue differences.

How does gradient mode work?

Gradient mode creates smooth color transitions between your base color and a target color. Choose both colors, set the number of steps, and the tool interpolates evenly between them in RGB color space. Useful for creating tint/shade scales or smooth background gradients.

Is my data safe when using this tool?
