CDOT uses deep yellow or amber for driving in snow, not super white or blue. Blue will seem brighter but you're really just seeing more light reflected and so it's only your perception. You want longer wavelength, warmer colors for fog and snow. If you want to see better, increase the intensity by getting higher power bulbs with color around 3200 K. In clear weather cooler colors like blue and white are better for the same reason they're bad in snow, they reflect better and so objects become clearer at greater distances.
