ColorYUV

The YUV color format describes a color by using the color components luminance and chrominance. The luminance component (Y) represents the brightness information of a color, the chrominance components (U and V) contain the color differences.

The YUV color format was developed for analog TV transmissions to provide compatibility between black-and-white television and color television: The luminance component is sufficient for black-and-white TV sets, whereas color TV sets need the additional chrominance information.
