weakly colored metals

The color of most metals is a variation of the brilliantly reflective white color of silver, but there are exceptions. In addition to the intensely colored metals copper, cesium, osmium, and gold (q. v.), certain of the metals display pinkish, yellowish, greenish, or bluish tones. Pinkish metals include manganese and bismuth. Silvery-yellow metals include strontium, barium, praseodymium, neodymium, europium, and ytterbium. Greenish-yellow metals include ruthenium and indium. Bluish metals include beryllium (also described variously as steel-, silver- or lead-gray), cobalt, zinc, tin, tantalum, and lead.
