Entschuldigen sie das ich Englisch schreibe.

My wiev is that it is the results that count, not the colours reflected. Ideally nothing should be reflected, every frequency should pass through. I tried to picture two of my lenses. One old Nikon 50-300ED with the multicoating of that time, and a fairly recent Voigtländer "Heliar" with a presumably better coating.

Unfortunately my snapshot camera does not obey orders. I set it at max 800ASA so as to avoid noise, but the camera likes to use the highest and noisiest setting and does not focus close. so the reflections in the "Heliar" are not easy to see.

However, it turns out that the snaps are too big to include and the process to shrink them is too laborious to undertake right now, so you will have to take my word for the difference. Lots of reflections in the Nikkor, very few in the "Heliar".
