But no one has mentioned it at all. I mean Hazel went into a lot of detail describing Percy's looks, saying she thought he was a god at first. But in three books where Percy is in them (BotL, TLO, and the SoN), no one has mentioned it at all, not even Percy himself. And trust me, when you have dark hair and grey hair starts growing in, people notice. Annabeth is blonde so maybe she just hides it better. But I could be wrong.
