The reason for red sunsets is that when the sun is low in the sky, its light has to travel through more of Earth's atmosphere before it reaches the observer. This causes the blue and green light (which have higher frequencies) to scatter and disperse, leaving mostly red and orange light to reach the observer. This red and orange light is able to survive being scattered in the atmosphere, hence creating a red sunset.
