To understand why these colors appear we must first understand the scattering of light. Scattering happens when small particles or molecules floating in the atmosphere cause photons of light to change directions. When the sun is low on the horizon, like it is during sunrise and sunset, the sunlight must travel more through the atmosphere. The long trip leaves the longer wavelength colors those reds, yellows, and oranges , but scatters the shorter wavelengths out.
A few clouds also help the sunrise become more vibrant, but not all types of clouds are good. The best clouds for vibrant colors are the middle-level or high-level clouds. Along with that, the advancing rain shaft that quickly followed popped in just in time for some of that light to be reflected in the form of a rainbow which is a scattering of light due to each rain drop.
Basically, we needed the first round of clouds to come through, mostly unobstructed at the exact right time and we needed the rain shaft to be exposed as well--a nd typically rain showers light enough to produce a rainbow are more common in the afternoon hours It really was a symphony of timing, science and a little bit of luck that brought a beautiful sight to mid-Missouri this morning.

Our planet, Earth, moves in space with seven other planets nearby. They all spin in circles on the spot, but also move in much larger circles around the Sun.
When the Sun is setting in Australia, this means our side of the planet is turning away from the Sun. Daytime happens when we have twirled to face the Sun directly — so its sunbeams travel very fast directly to us.
So we know why the sky is bright during the day and dark at night. In fact, all things are made of molecules, including you and me. But each molecule is much, much smaller than a grain of sand. The molecules then begin to play with the light — bouncing it back and forth between themselves.
