The timing relationship in a color video signal which keeps the hue of a color signal correct, measured in degrees. Color information is encoded in the video signal as the difference in phase between the sine peaks of the chrominance signal and the color burst subcarrier signal. If the two signals overlap exactly, then the phase difference is designated as zero degrees. If the sine signals do not overlap, the color phase can vary from 0 to 360 degrees. Each shift in the color phase represents a specific tint on the screen. If two sine waves are shifted one from the other by 180 degrees, then the colors are totally inverted.
