shading gradient

A shading gradient is a smooth transition between different shades, tones, or colors across a surface or image. It helps create a sense of depth, volume, and realism by mimicking how light naturally interacts with objects. For example, a sphere shaded with a gradient will appear three-dimensional because the lightest area suggests where light hits directly, while darker areas indicate shadows. Artists and designers use gradients to add subtlety and dimension, making images look more lifelike or visually appealing without harsh lines or abrupt color changes.
