Color Palette Generator: Build Harmonious Color Schemes From a Single Color
Enter a base color and generate complementary, analogous, triadic, and monochromatic palettes. Export as CSS variables, Tailwind config, or copy HEX values.
Introduction
Choosing colors is one of the hardest parts of design. You pick a blue you like, but then what? What accent color works with it? What shade should the background be? Our Color Palette Generator takes a single base color and applies color theory to produce harmonious palettes automatically. Choose from complementary, analogous, triadic, split-complementary, and monochromatic schemes, then fine-tune saturation and lightness until everything clicks. The palettes update in real time, and you can export them as CSS custom properties or HEX values.
Step-by-Step Guide
Enter your base color
Use the color picker, type a HEX code, or enter RGB values. This is your starting point. It could be a brand color, a color you pulled from a photo, or anything that feels right for your project.
Choose a harmony type
Select from complementary (opposite on the color wheel), analogous (neighbors on the wheel), triadic (evenly spaced), or monochromatic (same hue, different lightness). Each produces a distinctly different mood.
Export your palette
Click any swatch to copy its HEX value. Use the export button to get the full palette as CSS custom properties, SCSS variables, or a Tailwind config snippet.
Pro Tips & Best Practices
Start with your primary action color (the color of your main CTA button) and build the palette around it. This ensures your most important interactive element stands out naturally.
For dark mode, do not just invert your lightness values. Reduce saturation slightly and use darker, desaturated backgrounds. High-saturation colors on dark backgrounds cause visual vibration.
Test your palette with accessibility tools. A beautiful color combination that fails WCAG contrast requirements is not usable. Aim for at least 4.5:1 contrast ratio for text.
Common Mistakes to Avoid
Frequently Asked Questions
What is complementary color harmony?
Complementary colors sit directly opposite each other on the color wheel (like blue and orange). They create high contrast and visual tension, which makes them great for accent combinations.
Which harmony type is best for web design?
Analogous palettes are the safest choice for web design because they are naturally cohesive and easy on the eyes. Triadic palettes offer more variety but require careful balance. Complementary works well for accent highlights.
Can I save my palettes?
The tool does not store palettes server-side, but you can export the values as CSS or simply copy the HEX codes. For persistent palette management, paste the exported values into your design system.
