Why do the rings of a planet tend to have a large variety of different colors and shades?

Ringed planets a large array of differently-colored segments of the rings as opposed to one "blended" color for the entire ring, this has interested me for ages and I can't find out why this is. Thanks in advance!

The color is relatively uniform, it’s the density of the ring that changes. Thinner areas appear darker, since they reflect less light. Specifically for Saturn, these irregularities are caused by its moons. 

The largest gaps are cause by orbital resonances. Basically, each of Saturn’s moons tug on the particles in the rings. If the particle orbits an integer number of times for every orbit of the moon, it’s in a resonance. For example, the largest gap, called the Cassini division, is caused by a 1:2 resonance with the moon Mimas. Particles in the gap orbit twice for every orbit of Mimas, and this means Mimas pulls on them at regular intervals, which causes the orbit to be unstable. There’s hundreds of small gaps throughout the rings that you can’t normally see, and they’re mostly all caused of unstable resonances with other moons. Areas with more gaps seem darker, and with less gaps they look brighter.

The remaining gaps are cause by tiny moons orbiting within the rings. These small bodies either pull in ring particles, or throw them out of orbit, clearing a path.
