Metal is one of the trickiest material in a space. You want to match every details in the space so it has one unified metal color but not all products come in all metal finishes. I appreciate designers who attempted to at least coordinate and try make it work with similar tone metals. One of my all time favorite is copper! It has an aged look that glisten with warmth.

love how copper pipes are being incorporated in a useful way and exposed
Repurposed light fixture by Conant Metal & Light - the use of copper pipes as electric carrier and old insulator glass makes this a delicate and beautiful recycle piece of art [ I used this one with some customization at Catch restaurant over the communal table ]
