He's just pale like clout said, you think he doesn't look like a guy because of the swords? The hell? you see his forearms? That would be a pretty nasty girl if you asked me =x and also his clothes, for once we don't have a half naked guy like Albel or kuja - this guy actually has black baggy clothes, and his body is covered up in the right places, revealing his "muscles" in his forearms though, his clothes also look guyish, not girlish.

Heres the big picture, his lips are simply pale white, and everyone his a pinkish red color lip, thats the natural lip color.
