During sunrise or sunset, when the Sun is close to the horizon, the light must travel through more of the atmosphere than it does when the Sun is overhead. This results in more scattering of light, including longer wavelengths such as yellow, orange, and red, which creates colorful sunrise and sunset skies. Shorter wavelengths of light such as blue and violet don't get through as much as the longer-wavelength reds and orange, which are in turn reflected and scattered more and create stunning evening sunsets.
