The yellow/amber snow goggles are to keep out the vast amounts of UV light
which pour down on ski slopes. Without the goggles, you start getting mild
forms of snow blindness.
Such a purpose for filtering is hardly relevant on a puny 50 watt incandescent
bulb.

I do admit that blue light gives the least definition, but just because
the info is a bit fuzzy doesn't mean you should filter it out. Besides, in
fog, you don't really need fine definition (who wants to count the cracks
in the pavement?), but high contrast, so you can see the large objects (like
the edge of the road).
