Also my floors are a grey/brown

Two tone cabs but w the rustic floor pick hickory or oak w a medium dark brown stain for the lowers then the light paint on top. That melding the lower wood of cabs and floor surfaces would be nicer than wood floor and two paint colors... that makes 3 finishes ....

We did two tone white and navy, go with what you love! We had all white in our last two kitchens and wanted something different without totally giving up white.

@Ann544, can you show us your floors?

I agree with @herbflavor. I am no expert, but to me the gray base cabinets seem out of sync with the vintage-looking table. If you want to go two-toned, I would make the base cabinets a shade similar to the table and have the white uppers. Or you could make all the cabinetry white and have the table and floors be the only wood tones.

The table, the chandelier, the marble tile, the apron sink and the brass pulls all seem to have the same vintage-y feel to them. The gray base cabinets don't fit the vibe.

Ann, can I ask you a question about your marble backsplash. When you first installed your backsplash, did the marble look very dark gray? I ask because I have purchased marble backsplash that is white with gray veins, but when it was applied to the wall, it turned a very dark gray. It was only a few hours ago so may be the adhesive needs to dry and the tile will lighten, but I am very nervous so I have stopped the project. Did you experienced anything like this with your backsplash? Thank you in advance for your assistance. I am going nuts!
