paint color ideas?

I am redoing my kitchen, in small doses, since my remodeling budget is whatever I find under the couch cushions, and need some ideas. I have tile that is dark blue and teal, mini blinds that are a matching teal. I have an assorted collection of old copper things that I want to focus on and highlight, not the shiny orange jello mold stuff, but the old copper with the patina sheen. Eventually, I will hang the set of antique Portuguese pans from a rack above the bar, but since the bar isn't built yet, I'm going to hang them on the wall.

Currently the walls are white. What color would you paint the walls?
