The tint in the lens is a slight green, noticeable when changing from other glass such as the refit Retina-Xenar f/1.9 lens or the standard Voigtlander Color Skopar f/2.8. Thank you so very much about the information. It's an interesting collectable, but you could end up spending some real money to get it right. I was working on lenses like the Taylor Hobson 25-250 at the time and found my inability to adjust out all the errors in this old lens confusing and irritating. Don't expect it to perform like a modern Canon L zoom! It's a bit soft at the edges wide open at all focal lengths. It is a very old design, a complicated optic with adjustments everywhere. I repaired one about twenty years ago as a favour for a friend and it took me three weeks of working on it, testing (collimator, projection, MTF, film), making notes and putting it aside, having another go, before I got to the point where I felt the performance at the centre, long and short ends was balanced up to the point of being reasonable. Getting the optical element centration right is quite tricky and it would take a very good technician with good equipment to make it perform as it should. I would be cautious about having this lens repaired. The Zoomar does not have a colour cast under normal conditions, so it could be evaporated grease on the elements.
