Color harmonies are combinations of colors that look pleasing together, derived from their positions on the color wheel. Complementary colors sit opposite each other, triadic colors are evenly spaced at 120°, and analogous colors sit side by side.
Pick a base color and a harmony type. The tool rotates your color around the HSL wheel to generate the matching palette, showing each swatch with its hex code. Click any swatch to copy it to your clipboard.
Frequently Asked Questions
Q: What are complementary colors?
What are complementary colors? Two colors directly opposite on the color wheel (180° apart), like blue and orange or red and green. They create maximum contrast.
Q: What is a triadic color scheme?
What is a triadic color scheme? Three colors evenly spaced at 120° around the wheel, like red, yellow, and blue. Triadic schemes are vibrant but balanced.
Q: What is the difference between analogous and monochromatic?
What is the difference between analogous and monochromatic? Analogous uses colors adjacent on the wheel (e.g. blue, teal, green). Monochromatic uses only one hue with different lightness and saturation levels.
Q: Why does my palette look muddy?
Why does my palette look muddy? When mixing complements at equal strength, colors gray each other out. Reduce the saturation of one color or let one hue dominate to keep the palette fresh.
Q: Can I use these palettes for data visualization?
Can I use these palettes for data visualization? Yes, but check for colorblind-friendliness first. Use the Color Blindness Simulator tool on this site to verify your palette is distinguishable.
