Which design principle describes a gradual change in color from light to dark through a sequence?

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

Answer: (D)

Progression is exactly about a gradual change in color, value, or other attributes as you move through a sequence. When color shifts smoothly from light to dark across elements, the eye follows that ramp, creating a sense of flow, depth, and unity in the design. This smooth transition sets progression apart from contrast (sharp differences to emphasize), alternation (repeated differences), and repetition (repeating the same element). Using progression gives the layout a cohesive rhythm and guides the viewer’s gaze naturally along the sequence.
