He once was blonde like his daughter, but probably has white hair now, and maybe is partly bald. He's probably late-middle-aged, as they had their daughter rather late (we suppose), and aren't going to have any others. Otherwise, he's a European fairy tale king.
Hates puns. Fairly serious (though other people think he's funny). Basically, he's the Queen's straight man.
The queen's hair was black as night; and the king's had been, and his daughter's was, golden as morning. But it was not this reflection on his hair that arrested him; it was the double use of the word light. For the king hated all witticisms, and punning especially. And besides, he could not tell whether the queen meant light-haired or light-heired; for why might she not aspirate her vowels when she was ex-asperated herself?
