Color Banding
A symptom of insufficient color depth, color banding occurs when a monitor is unable to render smooth color gradients, and instead presents stripes or bands of color, especially in very light or very dark areas of an image. This occurs because the human eye is extraordinarily sensitive to color gradations, and can detect the change from one shade to another when color depth is limited.
Color Depth
A measurement of the number of bits used to represent the color of a single pixel. Greater color depth gives a larger number of distinct colors, i.e. millions or billions of colors, allowing for smoother color gradients. (See also: Deep Color)
