Complementary Colors: Maximum Impact Design
Colors that sit opposite each other — creating energy, tension, and unforgettable designs.
What Are Complementary Colors?
Two colors positioned exactly 180° apart on the color wheel
The Science of Color Opposition
Complementary colors create the strongest possible contrast between two hues. When placed next to each other, they intensify one another — a phenomenon called "simultaneous contrast." This is why red looks redder next to green, and blue appears more vibrant next to orange.
This visual tension makes complementary schemes incredibly effective for grabbing attention. However, it also makes them the trickiest to balance — too much of both colors can feel jarring and fatiguing.
⚡ Key Principle
Never use complementary colors in equal amounts. One must dominate (usually 70-80%) while the complement serves as an accent (20-30%). This creates impact without visual chaos.

White, black, or gray space prevents the colors from vibrating uncomfortably. Learn more in our Color Roles guide.
