- Triadic: 3 colors, 120° apart — vibrant, balanced, versatile
- Split-complementary: 3 colors — contrast with nuance, most versatile
- Tetradic/Square: 4 colors, 90° apart — rich, complex, requires careful balance
- Monochromatic: 1 hue, multiple lightness values — minimal, sophisticated, cohesive

Examples
Example 1: Complementary Scheme for a Call-to-Action Button
A designer is building a SaaS landing page with a blue primary color. They want a high-contrast accent color for the call-to-action button that creates visual energy and draws the eye.
Base color: #2563EB (blue)
Complementary: #EB6325 (orange)
Contrast ratio of orange on white: 3.1:1 (passes for large text)
Adjusted for AA compliance: #C44E0F (darker orange) — ratio 4.8:1
The complementary orange creates strong visual contrast with the blue navigation and body elements, making the CTA button immediately stand out. The designer uses the darker adjusted orange to ensure the button text remains accessible.
Example 2: Analogous Scheme for a Nature-Themed Website
A designer is building a website for an organic food brand. They want a calm, natural color palette that feels cohesive and earthy.
Base color: #4CAF50 (medium green)
Analogous colors (30° arc):
- #8BC34A (yellow-green)
- #4CAF50 (base green)
- #009688 (teal-green)
- #00BCD4 (cyan, extended)
The analogous palette feels natural and harmonious because all colors share a similar hue family. The designer uses the yellow-green for highlights, the base green for primary elements, and the teal for secondary accents. The result is a palette that evokes freshness and nature without feeling artificial.
Example 3: Triadic Scheme for a Children's App
A developer is building a children's educational app and wants a vibrant, playful color palette with good variety. A triadic scheme provides three equally spaced colors that are energetic but balanced.
Base color: #E53935 (red)
Triadic colors (120° spacing):
- #E53935 (red)
- #35E553 (green)
- #3553E5 (blue)
The three primary-adjacent colors create a lively, energetic palette perfect for a children's interface. The developer uses red for primary actions, blue for navigation, and green for success states and rewards. Each color is distinct enough to serve a clear functional role while the triadic relationship keeps the palette visually balanced.
