Internal bleaching is the most conservative way to change the value (color brightness) of a root canal treated tooth. Requiring you to drop the GP level to crestal level (I like to place a small Cavit plug coronal to this), I used a slurry of sodium perborate (Aluro) and Kor Night (16% carbamide peroxide) over a 6 week period to achieve a dramatic lift in color. The restoration on 21MP is planned for replacement next visit.
