What Are Tetradic Colors?

A tetradic color scheme uses four colors evenly distributed around the color wheel to form two complementary pairs. The result is a rich, varied palette that feels balanced because the colors are mathematically symmetrical — every color is matched by its opposite.

The most common tetradic arrangement is rectangular: base color at 0°, its complement at 180°, and two additional colors at 90° and 270°. This creates two complementary pairs (0°/180° and 90°/270°) that coexist harmoniously.

How to Use Tetradic Colors

Tetradic schemes are more complex than complementary or analogous palettes — with four colors you must be intentional about which one dominates. A proven approach is the 60-30-10 rule adapted for four colors:

  • Dominant (60%): One color is the primary background or surface.
  • Secondary (25%): A second color for major UI elements or sections.
  • Accent (10%): A third color for interactive elements and highlights.
  • Pop (5%): The fourth color used sparingly for attention-grabbing details.

Without this hierarchy, tetradic palettes can feel chaotic. With it, they feel rich and intentional.

When to Use Tetradic Palettes

  • Illustrations: Multi-color art benefits from the balance tetradic schemes provide.
  • Editorial spreads: Magazines and marketing collateral that need multiple coordinated hues.
  • Complex dashboards: Multiple data series that need distinguishable, harmonious colors.
  • Gaming interfaces: Character classes, factions, teams and levels that require distinct visual identities.
  • Event branding: Conferences, weddings and festivals with several simultaneous themes.

How OmniColor Generates Tetradic Palettes

Given a base hue H, OmniColor computes the other three colors at (H + 90°) % 360, (H + 180°) % 360, and (H + 270°) % 360. Saturation and lightness are preserved from the base color, so all four colors feel equally vivid and equally weighted. Change the base color and every hue shifts together, keeping the harmonic structure intact.
