how to decorate a kitchen w/ grey & black, w/o overly darkening the room. tip: use white walls, roof & display white bowls to brighten the room. tip add a pastel colour to add femininity & softness to the concrete floors & table.
I like the continuous path on the left. you can combine pavers to make big slabs. note that from this angle, it's all vertical, but from the side you'd see how the horizontal path goes. you would walk a wavy line over all these straight ones.
