≈ Burgundy#6A002A ≈ Medium Brown#6A4000

Tetradic colors

A tetradic (rectangle) scheme combines two complementary pairs at 0°, 60°, 180° and 240°. It offers variety but needs one dominant color to stay balanced.

Monochromatic variants

Monochromatic variants keep the same hue and saturation and only change lightness, which makes them dependable for UI scales and subtle layered designs.
