Smog's brown color is often due to the presence of nitrogen dioxide, which reacts with sunlight to form nitrogen dioxide. This reaction is more common in urban areas with high levels of vehicle emissions and industrial pollution.
Nitrogen dioxide is a reddish-brown gas that contributes to the color of smog haze. It is produced from the reaction of nitrogen oxides with sunlight and other pollutants in the atmosphere. Nitrogen dioxide is a harmful air pollutant that can cause respiratory issues and contribute to the formation of ozone and smog.
Brown absorbs most wavelengths of light in the visible spectrum, reflecting back a range of colors. This absorption of light gives brown its characteristic dark color.
Hair color is determined by a pigment called melanin, which is produced by melanocyte cells in the hair follicles. There are two types of melanin - eumelanin, which gives hair black or brown color, and pheomelanin, which gives hair red or blonde color. The proportion and distribution of these pigments determine the color of an individual's hair.

The type of smog that produces the brown haze is known as a photochemical smog. This is seen when oil or coal is burned.
