Why not Create an Exotic Shader that when equipped, it changes its own color to match that of the exotic armor you wear, for instance, the shader would change to the same kind of green that matches the armamentarium or the White & gold tinge of the Crest of alpha lupi or even the metallic purple coloration of the Helm of Saint-14 & vice versa, If the player is not wearing any exotic armour it would change to be like as if you had your default shader equipped. [i]If it was to be made into reality it would have to be sold as extra DLC. With the hours & hours of coding & programming Bungie does, it would be one heck of a long shot to create an Exotic Shader like that.[/i]
