Does the color of the lenses tint the view through the binoculars (like sunglasses)?
High-quality multi-coatings typically give the lenses a subtle green and/or purple appearance- but because they are so highly-efficient, transmitting at least 99% of the light, they will not tint the view through the general purpose or astronomy binoculars. The exception are poor-quality (highly-reflective mirror-like) coatings, which can reflect away part of the color spectrum. For example, so-called “ruby” coating reflects away most of the red, which gives the view an unnatural green cast.
