Dear Michele:
You neglected to tell me how old your floors are. The duller spots are probably the consequence of the spilling of acidic substances on the floor, which etched it and made it duller. The darkening of the filler, could be just good ol' soil.
What I would do if I were you, is to have a proficient stone restoration contractor re-hone your floors with a good-quality low grit honing powder (150 grit is recommended), like MB-14 (
http://www.stonecarecentral.com). Once the floor is completely re-honed, if the filler is still darker, then it's probably stained (but somehow I doubt that); in which case you will have to poultice the stains off. Apply a good-quality stone impregnating sealer like MB-4, get hold of the right cleaners for routine care and… enjoy!
The same principle applies to your hone-finished black “granite” countertop. The only difference is that, once you have your countertop re-honed, you will have it treated with a good-quality stone color enhancer like MB-6. That will turn your stone permanently and uniformly black, thus minimi
