Understanding Color Theory
Color theory is the science and art of using color. It explains how humans perceive color, how colors mix, match or clash, the messages colors communicate, and the methods used to replicate color.
The Color Wheel
The color wheel is the foundation of color theory. It maps the relationships between hues and helps us understand which combinations feel harmonious.
Primary Colors
- **Red** — energy, passion, attention
- **Blue** — trust, stability, calm
- **Yellow** — optimism, creativity, joy
Secondary Colors
- **Orange** (Red + Yellow) — enthusiasm and warmth
- **Green** (Blue + Yellow) — growth, balance, harmony
- **Purple** (Red + Blue) — luxury, mystery, depth
Color Harmony
Color harmony describes arrangements of colors that feel balanced and pleasing. Designers use harmony rules to build palettes that support the desired emotion or task.
- **Complementary** — opposite hues that create strong contrast
- **Analogous** — neighbors on the wheel for serene results
- **Triadic** — three evenly spaced hues with energetic balance
Practical Applications
Apply color theory to craft clear hierarchy, guide the eye to important UI actions, reinforce brand personality, and ensure accessibility through sufficient contrast.
