I always thought that blue was my favorite color. It was the color of Aang's tattoos, the color of water. Blue was peaceful; blue was tranquil. Blue represented everything that I loved in life. I controlled that color in my bending. Blue was connected to me in a way that I, nor anyone else, could understand.
But looking into his eyes, I knew that blue wasn't my favorite color.
Gold was.
Gold was alive; gold was passionate. Gold represented everything that blue did not. It gave things meaning, passion. Gold was life; gold was Zuko.
