"Gold is a yellow metal?" It ain't analytically so!

Proof at last that "Gold is a yellow metal" is not analytic, pace Kant. Viva la Kripke!

Southampton scientists change the colour of gold (From the BBC)


For this very reason all analytic judgments are a priori even when the concepts are empirical, as, for example, "Gold is a yellow metal," for to know this I require no experience beyond my concept of gold as a yellow metal. It is, in fact, the very concept, and I need only analyze it, without looking beyond it elsewhere.
