I think the greyish tone suits the character - looking at the original, the grit and grain very often look Rei look grey!
Makes it a little bit darker, and Rei is a dark and depressive character. (which is why we like it when she's smiling)
also anime characters do look like Grays when you remove the hair. HAH.
