A friend of mine had black stained hardwoods in her previous home and it does look really good, especially with a blue/slate grey wall color. However, about a year and a half after the floors were finished she would go over high traffic areas with a black sharpie marker. I’m not sure if bamboo will have the same type of wear as oak, but check into it.

I can’t remember if you are keeping the carpet in the living room area or not. If you are keeping the carpet, the blue/slate grey color may look darker in that room. I say this because we actually painted our bedroom the color blue that was in my friends house with the black floors. Our blue is much darker than hers was, since our floors are lighter. But, you probably know better than me how color hues are pulled from different surroundings. I would pick up some paint cards to see how dark or light they look against your flooring samples.

Hope you all are well.
