Metal colors in product design refer to the application of various metallic finishes on materials such as plastics, metals, or ceramics. These finishes can range from a metallic sheen to a brushed or textured effect, and are used to enhance the visual appeal, durability, and perceived value of products. Common metal colors include silver, gold, brass, copper, and chrome. Designers choose these colors based on the product's intended use, target audience, and branding requirements.
