Hi Lite in California does custom matching of colors and finishes. I bought their barn wall lights and they are perfect. I went through 2 manufacturers and returns for the right lights.

Those particular lights were purchased from Barn Light Electric. They are handspun from steel and finished with porcelain enamel. That color is called Jadite.
