That was funny.

In the comic from Mr. Kurumada, the colour page of Camus is wearing … red nail polish. A French GUY wearing red nail polish… may be this is just fashion, really no idea why. Also he has red hair in the comic ( so Camus is actually Ginger people?)

But then on the animation Camus's hair is Blue, and they get rid of the Nail polish thing. Milo has the Nail Polish Instead Coz his special attack ‘Scarlet Needle' need that effect so… but why Camus wearing that? Just guess ….
