There is a specialty lighting store near me that I am going to soon with photos to work on lighting at my house. I will show them your photo and see if they have an idea. Probably won't be till Fri or Sat but will get back to you.

A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

i love the dark flooring. what is the brand and the colour of the tiles...

What is your climate? And any activities you want for each terrace? Dining? Kids' play space? A water feature of some sort would be lovely. Could add some fake lawn (putting green even!) for part. This product has come a long way!
