What is a complementary color scheme?

A complementary scheme uses two colors opposite each other on the color wheel, for example blue and orange. This creates strong contrast and visual energy, making it effective for call-to-action buttons and highlights.

What is the difference between triadic and tetradic schemes?

Triadic uses three colors evenly spaced around the wheel at 120 degrees apart. Tetradic uses four colors forming a rectangle on the wheel at 90 degrees apart. Tetradic offers more variety but can be harder to balance.

How do I use the CSS variables output?

Click Copy CSS Variables to copy a :root block with --color-1 through --color-N custom properties. Paste this into your stylesheet, then use var(--color-1) in your CSS rules to reference each color.

Can I enter colors in formats other than hex?

The base color input accepts hex codes. You can type any valid 6-digit hex value like #ff5733. The tool then shows RGB and HSL values for all generated colors in the color details table.

Which scheme works best for web design?

Complementary works well for high-contrast sites, analogous for calm content-heavy pages, and monochromatic for minimal or corporate designs. The right choice depends on your brand personality and content type.
