Are we talking about metal here, or the description of a colour? Also, how does white gold get to be white?
                        
                           Effsee, I was trying to explain the use of the words red-gold as they are often used by writers and poets. Do you want a metallurgy lesson or what?

                           One does not go into a jewellers and ask for red gold; therefore I think that in the several contexts cited, the descriptive words "red gold" were born out of the imagery of folklore, magic, sagas, poetic licence and even Pre-Raphaelite paintings!
