Gold is most likely found in traditional and transitional rugs. The color gold inspires thoughts of royalty and elegance, lending itself to the sophisticated patterns and motifs of the traditional rug style. Gold is also sometimes used in contemporary rugs as well, where it gives warmth to designs that can sometimes be sharp and modern.
Burgundy, brown, green, and blue are colors that are commonly paired with gold in traditional rugs. Gold can sometimes be considered a neutral, and easily opens up small spaces. Mixed metals are popular as well, so don't shy away from copper or silver accents in small doses.
