Question:

Is pollution the cause of red sunsets?

Answer:

The truth is that tropospheric aerosols, when present in abundance as they often are over continental areas, do not enhance sky colors, they subdue them. Clean air is, in fact, the main ingredient common to brightly colored sunrises and sunsets.
