orange

The Periodic Spiral assigns the color orange—one could also describe this hue as golden—to phosphorus, lanthanum and the lanthanons, rhenium, gold, and bismuth. Of these elements, only gold is actually golden, or yellow-orange, in color. However, gold, when finally divided, may be black, ruby, or purple. Similarly, elemental phosphorus exists under ordinary conditions in yellow, red, purple and black categories.
