Tetradic Colors: Four-Color Mastery

The most complex harmony — two complementary pairs for comprehensive brand systems.

Understanding Tetradic Harmony

Tetradic (also called rectangular or double-complementary) schemes use four colors arranged into two complementary pairs. This creates the richest possible palette while maintaining mathematical harmony.

The colors form a rectangle on the color wheel, with each diagonal representing a complementary relationship. This means you have maximum variety — warm and cool colors, high and low contrast options.

Advanced Warning

Tetradic is the hardest scheme to balance. With four competing colors, chaos is one wrong decision away. If you're new to color theory, start with analogous or split-complementary first.

When Tetradic Makes Sense

✓ Use When

  • • Building comprehensive brand systems
  • • Data visualization with 4+ categories
  • • Large websites with many sections
  • • Products needing variety (seasonal)
  • • Gaming and entertainment brands

✗ Avoid When

  • • You're new to color theory
  • • The brand needs simplicity
  • • Working on single-page designs
  • • Minimal/clean aesthetic required
  • • Time is limited for testing

The Key to Tetradic Success

The secret is brutal hierarchy. Even though you have four colors, treat them unequally:

Dominant (50-60%)

Your primary brand color — backgrounds, headers

Secondary (20-25%)

Supporting color — cards, sections

Tertiary (10-15%)

Accent color — buttons, links, icons

Accent (5-10%)

Rare highlights — alerts, special badges

Balancing Tips

  1. 1

    Never give equal weight

    If all four colors appear equally, the design will feel chaotic. Commit to hierarchy.

  2. 2

    Separate complementary pairs

    Don't place direct complements adjacent to each other — add neutrals between them.

  3. 3

    Desaturate for sophistication

    Muted tetradic palettes feel refined; saturated ones feel playful or chaotic.

  4. 4

    Use neutrals liberally

    White, black, and gray provide crucial visual rest. Learn more in our Color Roles guide.
