Color Palette Generator

Create beautiful, harmonious color palettes using color theory. Pick a seed color, choose a harmony mode, and export for your project.

Quick Answer

Color palettes are built using color theory harmony rules on the HSL color wheel. Complementary colors sit 180 degrees apart, analogous colors are within 30 degrees of each other, and triadic colors are spaced 120 degrees apart. A well-balanced palette typically includes 5-7 colors: a primary, secondary, accent, and neutral shades for backgrounds and text.

About This Tool

The Color Palette Generator uses established color theory principles to create harmonious color combinations from a single seed color. Whether you are designing a website, building a brand identity, or choosing colors for a presentation, understanding color harmony is essential to creating visually cohesive work.

Understanding Color Harmony

Color harmony refers to the aesthetic relationship between colors when used together. The concept is rooted in the color wheel, first developed by Sir Isaac Newton in 1666 and refined by artists and scientists over centuries. The six harmony modes in this tool each leverage different geometric relationships on the color wheel to produce naturally pleasing combinations.

Harmony Modes Explained

Complementary pairs colors directly opposite each other on the wheel, creating high contrast and visual energy. Analogous selects neighbors on the wheel for a serene, unified feel. Triadic spaces three colors equally around the wheel for vibrant, balanced palettes. Split-complementary offers the contrast of complementary with less tension by using the two colors adjacent to the complement. Tetradic (rectangle) uses four colors forming two complementary pairs, offering rich variety. Monochromatic varies only lightness and saturation of a single hue for elegant, cohesive designs.

Choosing the Right Palette

For websites and apps, limit your main palette to 3-5 colors and use the 60-30-10 rule: 60% dominant color, 30% secondary, and 10% accent. Ensure sufficient contrast between text and backgrounds for accessibility. Tools like our Color Contrast Checker can verify WCAG compliance. Consider your audience and the emotions different colors evoke: blues convey trust, reds signal urgency, greens suggest growth, and warm tones feel approachable.

Exporting Your Palette

This tool supports three export formats. CSS Variables integrate directly into any web project. The Tailwind Config format drops into your Tailwind CSS setup for utility-class access. JSON export works for design tokens, Figma plugins, or any programmatic color workflow. Lock individual colors to preserve them while experimenting with new seed colors.

Frequently Asked Questions

What is color harmony and why does it matter?
Color harmony is the theory that certain color combinations are inherently more pleasing to the eye. These combinations follow geometric relationships on the color wheel. Using harmonious colors in your designs creates visual coherence, guides the viewer's attention, and evokes the right emotional response. Dissonant color choices, on the other hand, can make designs feel chaotic or unprofessional.
Which harmony mode should I choose for my project?
It depends on your goals. For high-energy, attention-grabbing designs (marketing, CTAs), use complementary or triadic. For calm, professional looks (corporate sites, portfolios), analogous or monochromatic works best. Split-complementary offers a good middle ground with contrast that isn't overwhelming. Tetradic gives the most variety but requires careful balance to avoid visual clutter.
How do I ensure my color palette is accessible?
Accessibility requires sufficient contrast between text and background colors. WCAG 2.1 recommends a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (AA level). Use our Color Contrast Checker tool to verify your combinations. Also consider color blindness: avoid relying solely on red/green distinctions, and test your palette with color blindness simulators.
Can I use this palette for print projects?
The colors generated are in RGB/Hex format, which is designed for screens. For print, you'll need to convert to CMYK, and some vibrant RGB colors may not reproduce accurately in print (they fall outside the CMYK gamut). Use a tool like Adobe Illustrator or an online CMYK converter, and always request a proof from your printer before a full run.
What does locking a color do?
Locking a color preserves it when you randomize the seed color or switch harmony modes. This is useful when you've found one or two colors you love and want to explore different combinations around them. Locked colors stay in their position while the remaining palette colors regenerate based on the new seed.
