Just as different rose colors have different meanings, the same goes for carnations, as well. For instance, pink signifies "I will never forget you." Red says, "My heart aches for you," as well as expresses admiration. Purple communicates hostility and ill will, and striped carnations imply, "I'm sorry; I can't be with you." White is lovely, as it conveys pure love and innocence, while yellow indicates disdain and rejection.
