Certainly, some old gold was reddish, and some old gold is better than some new gold, but not necessarily. Only the name. Many goldsmiths use all three expressions interchangeably, as I do. However, the words rose and pink carry softer overtones, so I tend to use red to denote a deeper red, and pink or rose to denote a softer, warmer colour. It is not often realised that there are only two metallic elements which are not silvery coloured.
Gold is yellow, and copper is red.
