What is Color Theory?
Color theory is a set of principles and guidelines that explain how colors interact with each other. It encompasses the study of color relationships, harmony, and the psychological effects of color. By understanding these principles, designers can create more effective and visually appealing designs.
The Color Wheel
The color wheel is the foundation of color theory. It's a circular diagram that shows the relationships between different colors. The traditional color wheel consists of:
| Color Type | Colors | Description | Examples |
|---|---|---|---|
| Primary | Red Blue Yellow | Cannot be created by mixing other colors | Foundation of all other colors |
| Secondary | Green Orange Purple | Created by mixing two primary colors | Red + Blue = Purple |
| Tertiary | Red-Orange Yellow-Green Blue-Purple | Mixing primary and secondary colors | More nuanced color variations |
Color Relationships
Understanding how colors relate to each other is crucial for creating harmonious designs. Here are the main color relationships:
Color Relationship Types
Complementary
Opposite on color wheel
High contrast, vibrant
Analogous
Adjacent on color wheel
Harmonious, pleasing
Triadic
Evenly spaced around wheel
Balanced, vibrant
| Relationship Type | Position | Visual Effect | Best Use Cases | Examples |
|---|---|---|---|---|
| Complementary | Opposite on wheel | High contrast, vibrant | Call-to-action buttons, highlights | Red + Green |
| Analogous | Adjacent on wheel | Harmonious, pleasing | Backgrounds, nature themes | Red + Orange + Yellow |
| Triadic | Evenly spaced (120°) | Balanced, vibrant | Brand colors, logos | Red + Blue + Yellow |
| Split-Complementary | Base + adjacent to complement | Contrast without tension | Web design, interfaces | Red + Green + Blue |
Analogous Colors
Analogous colors are next to each other on the color wheel. They create harmonious and pleasing combinations. Examples include:
- Red, Orange, and Yellow
- Blue, Purple, and Magenta
Triadic Colors
Triadic colors are evenly spaced around the color wheel, creating vibrant and balanced combinations. The primary triadic combination is Red, Blue, and Yellow.
