Gold and Copper
The two colored metals are copper (Cu Z=29) and gold (Au Z=79). There are other metals that have a hint of color, for example cesium has a golden tint and some samples of cobalt have a bluish tinge, but the color is not as pronounce as Cu and Au.
There are not many contributors to this forum that know why copper is copper-colored, and gold is gold-colored.
