I think white is more visible.....if one is actually looking. There in lies the problem, most car drivers are too busy talking on cell phones, fiddling with a map or messing with their Tom Tom to look out for any traffic let alone motorcycles. That said I am not sure it makes much difference what color your helmet is.

I do not know of any definitive studies that show a safety increase with any color.

There was a great debate over the best color to put on fire trucks about 15 years ago. For technical reasons Lime Green and White were deemed ideal. The problem was that neither color was recognized by the public as a fire truck color (red has been the traditional color) and there were the same or slightly higher number accidents. Go figure.

I think the bottom line is that we should make ourselves as visible as possible and maintain a high level of defensive driving. IMHO.

PS I wear a white helmet (Simpson Voyager).....it was the last helmet I had from when I raced stock cars.
