A) The property of colour which relates to the amount of white light in the color. Highly saturated colours are vivid, while less saturated colours appear pastel. For example, red is highly saturated while pink is the same hue but much less saturated. b) In signal terms, saturation is determined by the ratio between luminance level and chrominance amplitude. It should be noted that a vectorscope does not display saturation; the length of the vectors represents chrominance amplitude. In order to verify that the saturation of the colours in a colour bar signal is correct, you must cheque luminance amplitudes with a waveform monitor in addition to observing the vectors. c) The amount of gray, as opposed to hue, in a color. See Hue.
