Abstract: An apparatus for correcting errors in color signal transitions includes a signal scaling device and a signal mixing device. A wide bandwidth luminance signal is applied to the signal scaling device which develops a limiting signal for a particular narrow bandwidth color difference or primary color signal. This limiting signal is mixed with its associated color difference or primary color signal by the signal mixing device. The output of the signal mixing device is a color difference or primary color signal that has amplitude values less than or equal to the amplitude values of the limit signal.
