I am sure CC can give a very good picture, but it seems I'm going to need some help to get there.

What is happening is the sharp monochrome contrast transition is being interpreted by the chroma circuits as a color signal. To fix this (assuming a good combo of fine tune and chroma level don't fix it) you will need to re-align the chroma bandpass amp and or the RF/IF system...Or you could just live with it (as I've done on a couple of sets until I can get an alignment rig together and practice).
