  • NTSC receivers have a tint control to perform colour correction manually.
  • The tint control is normally set by sight to create satisfactory skin tones in a picture.
  • The PAL standard automatically cancels hue errors by phase reversal, so a tint control is unnecessary yet Saturation control can be more useful.
  • Any phase errors could then be compensated for by using a tint control knob on the front of the set, normally unneeded on a PAL set.
  • Television sets produced in recent decades typically include a ( sometimes non-defeatable ) distortion of the color decoding spectrum, to minimize the visual effects of phase error and lessen the need to adjust the tint control.
  • 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.
  • Most TV sets designed for these later standards lack tint controls, as PAL and SECAM are not supposed to experience the problems a tint control would correct . ( This leaves the viewer unable to correct for color errors originating at the transmission site, however . ) Multistandard sets have tint controls for NTSC viewing, but the controls are inoperative when watching PAL or SECAM signals.
