Actually, this isnt true. (Speaking from many years of laser/optics
experience) Red is the preferred color for fog, but is illegal on the
front of cars, where amber is second best with yellow following. White
reflects off the water too much, where red will not.
Theres a whole lot of math that goes along with it, but I didnt
understand it then, and I doubt I would today either.. :)
