Except for black, which other hair colours do आप think will suit Magnus?

This is just my personal opinion but I think he'd look great with a rich टील, टीला, गहरा हरिताभ नीला color. I think it would look very interesting with his eye color, too.

इंद्रधनुष coloured. That's how he's described in the books, unless I'm mixing up here, and I think it सूट्स him.

Purple
