Too much or just perfect?

I've been dreaming of renovating our little galley kitchen for four years.  Nothing huge - just little things to modernize it and bring some design-love to the outdated space.  Of course, I have been storing up ideas for all these years... here's a new one: Black Tile for the walls.  Hmmm... too dramatic?  I want the kitchen to be all black and white w/ a little grey/green.  What do you think?
