When it comes to mixing metals in room decor, there are several combinations that work well together. For instance, pairing warm metals like gold or brass with cool metals like silver or chrome can create a visually appealing contrast. Additionally, mixing similar metal tones with slight variations in finishes can add depth and dimension to your space. While there are no strict rules for which mixed metals go together, it's important to maintain balance and harmony by selecting a common theme or color palette that ties the different metal finishes together.
