What term describes the quality of color in a video?

The quality of color in a video is best described by the term "Chrominance." Chrominance refers to the component of the video signal that conveys the color information, including both hue and saturation. This is essential for understanding how colors appear in a video image, as it distinguishes color information from the brightness, or luminance, aspect of the image.

Saturation, while related, specifically measures the intensity or purity of a color in relation to gray; it does not encompass the whole quality of color as chrominance does. Hue describes the type of color itself, such as red, blue, or green, which is just one aspect of the overall color quality. Contrast addresses the difference in brightness between the lightest and darkest parts of an image, which can affect how color appears but does not define its quality directly.

Thus, chrominance is the most comprehensive term to describe the quality of color in a video, as it includes essential aspects of color perception.
