they look distinctly brown to me. I will ask my fiancee' what color

Is there some difference in visual perception going on here?
Were they *always* brown? Age-related yellowing of the eye's lens could be a factor.
Surely someone here owns a vintage spectrophotometer, or at least a camera and
grey card.
