Why do sunrises and sunsets typically display predominantly red and orange hues?

Answer

The light has to travel through more atmosphere, scattering away most of the blue

When the sun is low, the sunlight must traverse a greater thickness of the atmosphere, which results in most of the shorter blue wavelengths being scattered away before the longer wavelengths, like reds and oranges, reach the observer's eyes.
