If you go with that dark grey with the cabinets, I’d say to keep all the other tones and colors going into the space light — especially if you only have one window!! Try white quartz countertop which is very durable (like a Caeserstone – they sell at Home Depot etc.) or porcelain slab like we did in OMG We Bought A House!!
Then, a pretty subway tile backsplash with grey grout would be really pretty! And some brushed nickel or brass cabinet pulls!!
