“My hair is naturally blonde... Just for the record. ~ Jace”

“Yeah, well, you clearly also couldn't be bothered to call me and tell me you were shacking up with some dyed-blond wanna-be goth you probably met at Pandemonium. After I spent the past three days wondering if you were dead.""I was not shacking up," Clary said, glad of the darkness as the blood rushed to her face."And my hair is naturally blond," said Jace. "Just for the record."Simon, Clary, and Jace, pg. 115”

“Blonde hair and black hair are the two poles of human nature. Black hair signifies virility, courage, frankness, activity, whereas blonde hair symbolises femininity, tenderness, weakness, and passivity. Therefore a blonde is in fact doubly a woman. A princess can only be blonde. That's also why, to be as feminine as possible, women dye their hair yellow- but never black""I'm curious about how pigments exercise their influence over the human soul", said Bertlef doubtfully."it's not a matter of pigments. A blonde unconsciously adapts herself to her hair. Especially if the blonde is a brunette who dyes her hair yellow. She tries to be faithful to her hair colour and behaves like a fragile creature, a shallow doll, she demands tenderness and service, courtesy and alimony, she's incapable of doing anything for herself, all refinement on the outside and coarseness on the inside. If black hair became a universal fashion, life on this world would clearly be better. It would be the most useful social reform ever achieved.”

“Now before we do any digging around in that blond head of yours to find out the truth, I suggest you cool your temper. And I know just where you can do that best.”Jace blinked. “Are you sending me to my room?”

“Being blond is not a hair color, it's a lifestyle.”

“Jace shook his blond head in exasperation. "You had to make a crazy jail friend, didn't you? You couldn't just count ceiling tiles or tame a pet mouse like normal prisoners do?”
