Would that I could strike out at her torment, wearing a sash of said colors… casting down those that would cause her such anguish and annoyance today… Drive a lance through the heart of the vile Server Knave (no king, he!) and then sweep my lady off of her feet for a comfortable time together, free of struggle and full of pleasure.

Blue (Azure)- Truth and loyalty
