Use Black with Brown Light Fixtures?

If I use brown light fixtures, can I still use some black on my walls, such as picture frames?

Giorgina: I am so terribly sorry that I haven't been able to answer literally dozens and dozens of questions that readers have sent us. We're just so swamped and don't have the time to keep up anymore.

Rather than leave them waiting in the queue, I've decided to post the questions here anyway in hopes that other readers might be able to help answer some of these questions. Please, if you're reading this and want to help out, leave your comment and try to help if you can. Thank you!
