The one-of-a-kind vintage finish of this item has a silver base with light golden inlay accents, and will likely appear to be more silver than pictured. This is not a defect, but a uniqueness of this particular finish style.
I could see this a a potential DIY project - paint bulbs black and then carve some of the paint off to let the light shine through. While not specific for outdoor use, these Astral Lights would be a lovely addition to an enclosed porch :)
