I love those white eyelashes. It reminds me of this one FF7 Djka (Emily Kujoh, I think or one of her circles) who always drew Rufus with these white-blond eyelashes. Hrrrrnghh!
Originally, PoJ ren came with a blond wig! So I think it's safe to say he's naturally fair. And Janus didn't want the white eyelashes, so there you go.
I would go upstairs and squeeze him but eider is still sleeping. ^_^
