Applied colour theory: the colour wheel and harmony

Colour theory gives names to what looks right. Once you know a few terms, choosing colours becomes a method instead of a guess.

The three properties of a colour

  • Hue — the colour family: red, blue, green.
  • Value — how light or dark it is.
  • Saturation — how intense or muted it is.

Rooms usually feel calmer with muted colours and varied values; strong saturation works best in small doses.

Classic harmonies on the colour wheel

  • Monochromatic — one hue in several values. Calm and elegant.
  • Analogous — neighbours on the wheel, such as blue, blue-green and green. Harmonious and natural.
  • Complementary — opposites, such as blue and orange. Lively; let one dominate.
  • Split-complementary — a colour plus the two neighbours of its opposite. Contrast with less tension.
  • Triadic — three colours evenly spaced. Vibrant; use muted versions indoors.

Warm and cool

Reds, oranges and yellows feel warm and seem to come forward; blues and greens feel cool and seem to recede. That's why cool colours can make a small room feel larger.

Putting it to work

Pick a harmony, then apply the 60-30-10 proportions: 60% main colour, 30% secondary, 10% accent.
