colour: Tristimulus measurement and chromaticity diagrams: …their different Y values (luminance, or visually perceived brightness).

television: Basic principles of compatible colour: The NTSC system: …amplitude modulated by (1) the luminance signal, to represent changes in the intended luminance, and (2) the chrominance subcarrier, which in turn is amplitude modulated to represent changes in the intended saturation and phase modulated to represent changes in the intended hue. When a colour receiver is tuned to the…

television: Basic principles of compatible colour: The NTSC system: …when viewing white light, the luminance transmission carries the impression of fine detail. Because it employs methods essentially identical to those of a monochrome television system, it can be picked up by black-and-white receivers. The chrominance transmission has no appreciable effect on black-and-white receivers, yet, when used with the luminance…
