Color schemes with Medium Blue

Built by rotating the hue in OKLCH, so every colour keeps the same lightness instead of drifting the way an HSL rotation does. Each one is named and clickable.

Complementary

The colour directly opposite. Maximum contrast — good for a single accent against a dominant colour.

Analogous

Neighbours on either side. Calm and cohesive, because nothing fights for attention.

Triadic

Three colours evenly spaced around the wheel. Vivid but balanced.

Split complementary

The two colours either side of the opposite. Nearly the contrast of a complementary pair, with less tension.

Tetradic

Two complementary pairs. The richest scheme, and the easiest to overdo — let one colour lead.

Monochromatic

One hue at several lightnesses. Reliable for interfaces, where hue changes read as meaning.

Variations
