The word comes from the Greek "chroma," which means color. Chrome is a metal that forms very hard steel-gray masses that gleam a silver color. Less than 3% mixture of chromium to steel produces and extremely hard alloy. It is used for plating base metals that easily corrode. It receives its name from the green, orange, yellow, and red colors which emanate from the oxide and acid which contacts specific minerals and yields a chrome-green, chrome-yellow, and other color pigments.
