When it comes to marble, there are many different colors out there. Some of the most expensive marbles in the world have a black base with white or yellow veining running throughout.
Most people choose light-colored stone flooring because they think it is easier to keep clean and beautiful looking. While this may be true for you at first, you should consider that if your marble has dark veins then cleaning will be more difficult than on lighter stones, and if it is polished correctly then it can look just as good as its counterparts.
If you want your floors to shine through, especially when lit by natural sunlight; go with a darker color like deep reds or even blues. The darker the color, the more reflective it is, so this will make it more vibrant and beautiful over time while also ensuring that you don't have any trouble shining it up.

It's worth noting that you can also match your kitchen countertops with your floor if you want a more symmetrical look.
