Frequently asked questions

What is a complementary color palette?

A complementary palette pairs your base color with the color directly opposite it on the color wheel (180° away in hue). The high contrast makes complementary pairs great for call-to-action buttons and accents that need to stand out.

What is the difference between analogous and triadic colors?

Analogous colors sit next to each other on the color wheel (about 30° apart) and feel calm and cohesive. Triadic colors are spaced evenly 120° apart, giving a vibrant, balanced scheme with more contrast. Use analogous for backgrounds and triadic when you need three distinct brand colors.

How many colors should a website palette have?

Most design systems use one primary color, one or two accents, and a range of neutrals — roughly following the 60-30-10 rule (60% dominant, 30% secondary, 10% accent). A monochromatic or analogous palette plus one complementary accent is a reliable starting point.

What is a monochromatic color scheme?

A monochromatic scheme uses one hue at different lightness and saturation levels. It always looks harmonious because every color shares the same base hue, which makes it a safe choice for minimalist interfaces and data visualizations.

Can I use these palettes commercially?

Yes. Colors themselves cannot be copyrighted, and this tool simply computes standard color-wheel harmonies from your input. Use the generated palettes in any personal or commercial project.
