uck...it depends cause Im looking at kaito at this very moment..like if they can rock it. If they make the color look good on them then thats the color I like~ so it can be any...But I'll say blue since kaito is who I see atm~xD
What the. Brown, plain and simple is the best. It works well on ANY anime character, and that's an affirmative.
Go on, try it out and imagine it on any anime character male/female that you know. Light brown shades, Dark brown shades, Brown.
