Because the NTSC color television standard relies on the absolute phase of the color information, color errors occur when the phase of the video signal is altered between source and receiver. To correct for phase errors, a tint control is provided on NTSC television sets, which allows the user to manually adjust the phase relationship between the color information in the video and the reference for decoding the color information, known as the "color burst", so that correct colors may be displayed.
