The best color lens depends on lighting conditions. Grey lenses cut all light equally and are the best for viewing colors as they truely are. Yellowish, persimmon, amber, rose, etc cut light from the blue end of the color spectrum, which helps cut some of the blue haze from the sky, and enhances contrast of the red and green colors. These lenses are great for looking off into the horizon without seeing all the blue haze. The blue lenses cut more in the yellow end of the spectrum. Some people with color vision deficiencies may like the blue tints better. (Eight percent of males have some form of color deficiency.) Polarized lenses cut at least 50% of the light passing through the lens and are great for general outdoor conditions, but are dangerous in low light conditions, such as dusk to dawn. If you will ever need them at night, clear is the way to go if you only want one lens. Bottom line is there is no one color that is best for all conditions. Boils down to personal preference, and how many pairs of goggles you want to take with you. I have clear, polarized grey, and persimmon, and use them all depending on conditions. Probably wear the persimmon the most. Zeal goggles get my vote for best optical quality.
