No perceptible color changes, but a faint (thin) cataract on the left cornea acts much like one of my old Takumars... Slightly yellow. Normally, it's not noticeable. Not with both eyes open. With just the left eye open, I can't _see_ the color bias, but my vision is much less sharp. Hardly unusual... <g>
