Hello Samantha
Natural stone is exactly what you purchased. They change color abit but please do not go painting are something like that. Just leave them and they will return to the separate existence of the state was

While it does not sleep in anything, because it itself change the color if it is only very slightly. If it starts to fade because of the weather, just give it a shot with a pressure washer (just buy a good market for this job) in the spring, and it will be like new.

The black came from dust, mold, moss, hard water stain?? Hard to tell you what to do until we determine what is causing the problem. If hard water and can not be avoided, then seal with. I have this problem on my stucco house in pipe joints leaking. Once I sealed the plaster, no water problem. Weird when it rains these spots do not get wet ...

If there is dust, mold or moss, try using a scrub brush occasionally to clean the pores. Be gentle, you do not want to go through the larger holes.

It is a product manufactured by a company called Brintons you just leave the water on and turn the stone back to its natural color. It does not work as I sell it in gallons of very satisfied customers. You can find Brintons on the web. They do not sell by mail because of the difficulty of chemical diffusion, but if you contact them, they should tell you the nearest provider.
