Which design principle changes from one color to another repeatedly?

• A. Progression
• B. Repetition
• C. Alternation
• D. Contrast

Answer: (C)

Alternation in design is about repeatedly switching between colors as you move through a sequence of elements. This creates a back-and-forth pattern that the eye easily follows, giving the design a rhythmic, dynamic feel. In a pattern where colors swap between two hues across items—like a checkerboard or striped sequence—the color changes happen again and again, which is the essence of alternation.

This differs from repetition, where the same color is used over and over without changing. It also differs from progression, where the color shifts gradually in one direction across the sequence. And it’s not about making elements stand out through contrast; contrast focuses on difference for emphasis rather than a repeating color swap.
