I think there's a difference between the "regalness" of purple and of gold. Purple is regal if you're a grape. Purple is the lavender regalness of a queen. Gold is regal worldwide. Gold is a precious metal sought after in every culture. The Pack does not truly have gold coloring. They really have yellow, and, as another posters suggested, MUSTARD yellow.
Given the storied history of the Pack, the yellow should be switched to gold.
