There are many examples on houzz of contrasting counters for perimeter and island. For example butcher block on island and stone on perimeter or a solid color on one and something with movement on another. I would only mix two stones if one had movement and one was fairly solid. The stainless on perimeter and something else on island sounds good to me. Here is a pic of stainless counters with what looks like a stone breakfast bar. (I hope I understood your question right). http://houzz.com/photos/3137660

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

This project required a small renovation, where my clients wanted to create something simple and light, without costing a fortune. In the guest bathroom we were able to leave the plumbing as is and worked on replacing the WC, Shower and Vanity. In the laundry the area in the room behind the counter, storage area was pushed back allowing for a larger space within the narrow room. A new door was put in and a new window. Before: After: This extension of space allowed for the guest bathroom to be extended out as well to allow for a larger vanity and all round larger and more accommodating space. The counter top in the laundry is bamboo, the simple black tiles above and perhaps later down the clients will put up cupboards and shelving as suggested. Before: After: The light grey ceramic tiles on the floor replaced the dark ones that made the space feel small and cramped. The white on the walls and new lighting give a totally different feel to the room and makes it a far more welcoming space to work in. Check entire project here!
