Higher level dragons like elder dragons and ancient dragons are gold in color. Legendaries are white while revered share their color scheme with Odahviing, who is a red colored ancient dragon with blue markings.

Paarthurnax is in fact a unique elder dragon, he looks the same as them, except his wings are tatty and his horns and spines are chipped and broken. Other than that, his character model is pretty similar, except he's no longer shiny.
