What Is a Color Palette Generator?

A color palette generator uses color theory algorithms to create sets of harmonious colors from a single input color (the "seed" color). By applying established rules about color relationships on the color wheel, it produces palettes that feel visually cohesive and professionally designed — without requiring deep design expertise.

The output typically includes 4–7 colors suited for different UI roles: primary, secondary, accent, background, and text colors. Most generators also produce a full shade range (50 through 900) for each color, enabling detailed design systems.

How to Generate a Color Palette Online

1. Open the color palette generator at DevKits.
2. Enter a seed color — your brand color, a hex code, or pick from the visual color wheel.
3. Choose a color harmony rule (or generate all and choose your favorite).
4. Preview the palette with a UI mockup to see how colors work together in context.
5. Export as CSS custom properties, Tailwind config, JSON, or PNG swatch.

Color Harmony Rules Explained

Complementary

Two colors directly opposite each other on the color wheel (180° apart). Creates high contrast and visual energy. Example: orange (#FF5733) and its complement cyan-blue (#33CFFF). Best for CTAs and accent elements that need to pop against a primary color.

Analogous

Three colors adjacent on the color wheel (30° apart). Creates a harmonious, low-contrast palette that feels natural and calm. Best for backgrounds, ambient colors, and subtle variations in a UI section.

Triadic

Three colors evenly spaced (120° apart) on the color wheel. Creates vibrant, high-contrast palettes with visual balance. More complex to execute well than complementary, but very dynamic.

Split-Complementary

A base color plus the two colors adjacent to its complement. Less stark than pure complementary but still high-contrast. Often the most practical choice for UI design.

Tetradic / Square

Four colors evenly spaced (90° apart). Very complex palettes — works well when one color dominates and the others are used as accents.

Monochromatic

Multiple tints, shades, and tones of a single hue. Creates refined, elegant, or minimal aesthetics. Popular for professional and luxury brands.

Frequently Asked Questions

How many colors should a website palette have?

Most design systems work best with 3–5 base colors: 1 primary, 1 secondary, 1 accent, plus neutral (gray) and semantic colors (success green, error red). More than 5–6 distinct hues creates visual complexity that's hard to manage.

What's the difference between a tint, shade, and tone?

A tint is a color lightened by adding white. A shade is a color darkened by adding black. A tone is a color desaturated by adding gray. In HSL terms: tint = increase lightness, shade = decrease lightness, tone = decrease saturation.

How do I create a dark mode palette?

For dark mode, swap backgrounds to very dark variants of your primary hue (not pure black), use lighter tints for text (not pure white), and ensure all text-background combinations meet WCAG AA contrast requirements. The tool's accessibility checker makes this easy.

Can I export the palette to Figma?

The tool exports hex values that can be manually added to Figma's color styles. For automated Figma integration, export as JSON and use a Figma plugin that imports color token files.

Is the tool free?

Yes, completely free with no signup required.
