In the Bellows translation of Poetic Edda poem Reginsmal, Sigurd's reply to his dwarven foster father Regin's suggestion that he help him seek his revenge by killing Regin's brother Fafnir, who's turned into a dragon is:

Loud will laugh the sons of Hunding,
They who Eylima of life deprived
If the prince is more desirous
To seek the red-gold rings
Than to avenge the death of his father.

Red gold is probably a gold alloy with a red component. I always thought, when reading this stanza, that it symbolised personal glory over family honour. This legend is my very favourite Norse tale.
