It is used as a color synchronization signal to establish a reference for the color information following it and is used by a color monitor to decode the color portion of a video signal. The color burst acts as both amplitude and phase reference for color hue and intensity. The color oscillator of a color television receiver is phase locked to the color burst. A process in which the coloring in a television image is altered or corrected by electronic means. The phase of the chroma signal as compared to the color burst, is one of the factors that determines a video signal's color balance.
Higher numbers indicate bluer light, lower numbers indicate a warmer light.
The color temperature of the lighting must match the color temperature of the camera. In video this is accomplished by setting the white balance of the camera. Sunny Daylight is approximately 5500 deg. K. Overcast daylight is higher. Fluorescent Lights are approx.
