The tube is probably showing it's age a little. Turn the color control to minimum. If you notice a green tint, you may need to tweak the CRT bias controls. Those should be located on the 9-181 module. I think I remember some early '80's Zenith's having an auto kine bias (AKB) circuit, meaning there are no bias adjustments. About all you can do in that case is tweak the G2 control on the flyback.
