light closer in the yellow band of the color spectrum is less glarey to our eyes than light close to the blue light spectrum. (meaning why for decades automotive fog lights have had amber/yellow lenses.) Warmer light always seem have less glare irritation to the eyes from the reflected light from fog (or snow) at night. sort of causing less eye-squinting from the easier to look at warmer reflected light, allowing us to focus better on objects in the distance. The difference between a 2700~3000K warm white Flashlight and a 6500~7000K cool white flashlight beam in fog or a snow blizzard is very noticeable with the warmer light being much less eye glare.
