I have the exact same set, 'cept I had to drive to Toledo!
As to that color issue, it could be something simple as suggested, but I had another color Zenith that I has a helluva time getting color on... In any event, rest assured it is a color set... use my pics to remind you, lol.
Looks like yours has the original picture tube, because the greenish screen matches the tube surround. Mine has a rebuilt tube that's more blue/grey.
