Saturation (chroma, chroma gain, color)

Saturation (chroma, chroma gain, color)
A&V
• The intensity of the colors in the active picture. The voltage levels of the colors. The degree by which the eye perceives a color as departing from a gray or white scale of the same brightness. A 100% saturated color does not contain any white; adding white reduces saturation. In NTSC and PAL video signals, the color saturation at any particular instant in the picture is conveyed by the corresponding instantaneous amplitude of the active video subcarrier.
• The point on the operational curve of an amplifier at which an increase in input amplitude will no longer result in an increase in amplitude at the output.
