That is 100 percent correct. A color TV picture must be firmly locked in sync for the color to be stable. Poor horizontal sync, in particular, will cause color sync problems as well. I had a roundie color set years ago with very poor color sync, but I didn't know at the time (early 1970s) that the horizontal was tied in with the color. Had I known then what I know now about the link between solid horizontal sync and color sync, I could have enjoyed that set a little longer with a good picture. As it was, every time the color would go out of sync, I had to turn the tint control from one extreme to the other several times to get it to lock. That symptom alone should have told me right there something wasn't right with the horizontal, but I was a 17-year-old kid at the time puttering with the set at random and didn't know any better. Finally had to get rid of the set a year or so later, when the video output circuit board cracked while trying to replace the tube.
