Metal-coloured refers to something that has the colour of metal, which is often grey, silver or sometimes golden. However, there are several synonyms that can be used instead of metal-coloured, to describe the same hue. For instance, metallic can be used to describe the luminous and reflective colour of metal. Similarly, steel-grey is another synonym that can represent a metal-coloured shade, presenting a sleek and polished appearance. Bronze, copper or brass are also synonymous with metal-coloured, presenting a more rustic and warm tone. Silverish, pewter or chrome can be used to describe a bright and shiny metal-coloured hue. In summary, these synonyms provide a lot of flexibility and choice when it comes to describing a metal-coloured object or item.
