Good Morning, LICENCEDMECH:
Not knowing how old the set is, I would assume that there are some miles on the unit. And, obviously, there is an absense of red in the picture.
Check into this website and read Paragraph 25.4. It explains it better than I can:

As it says, it could be a bad color driver, a bad color decoder, or it could well be the picture tube, itself.

Zenith's are known for there crt (picture tube) problems. I've seen it from there delta gun crts to there inline gun crts. You've lost your red screen color due to a short in the red gun. To determine how bad the short is you need a crt tester/rejuvenator to run the appropriate tests. If the crt fails any of the tests and will not rejuvenate, the crt needs to be replaced along with #9-155 crt module(If this is a real old set) or motherboard(If this is a newer set). This is just a starting point when troubleshooting this type of problem.
