uibarbuttonitem tintColor

I have 2 buttons on a UIToolbar开发者_JAVA技巧, I'd like one to be tinted green and the other red. Can I do this using the TintColor feature. Or do I have to use images?

EDIT: I misread. If you want to tint the buttons individually, your only option is going to be images and custom views.

I would warn you though, this is a blatant violation of the HIG. I don't think it'll be liked by the review team.
