What does gradation involve?

Gradation involves a gradual transition or change in characteristics, such as color, size, or intensity, often seen in art, design, and natural phenomena. It creates a sense of depth and dimension by blending elements smoothly, enhancing visual interest and complexity. In other contexts, like education or assessment, gradation can refer to the systematic classification of levels or grades in a hierarchy. Overall, gradation emphasizes subtlety and progression in various fields.
