I think the image attached to post #25 does a pretty good job of teasing out the color bias, or lack of it, in some "alpha" binoculars. Whatever our individual perceptions of color may be, the binocular optics act as mild color filters that modify those perceptions. I don't see why everyone, regardless of their personal color perception, wouldn't find the Nikon in the image acting like a mild orange/red filter and the Zeiss acting like a mild green filter.</blockquote>
