Why do Curiosity and other ‘space cameras’ take photos in individual RGB layers?

The Short Answer
Cameras you're used to using are designed to be able to capture a full image quickly. This means that things don't have to stand still all that long (or may even be moving if you have a fast enough shutter speed). Cameras in space are optimized to have the smallest possible camera while providing the most capability, and their subjects are seldom moving. This means that instead of having 1 set of red pixels, 1 set of green, and 1 set of blue, you can have just one set of pixels that is three times as dense for the same size and power requirement. Then you can put a wheel with, say, 8 different filters and suddenly you can capture true color images as well as images that are in other areas of the spectrum. You get the capability of 8 cameras that are each 3 times the resolution, all in one.
