Actually that appears to be the graphic that we already have. It's green all the time on the my messages block. My suggestion is that if all the messages in the box have been read read, then that block would not be green but "greyed out" (no fill color) like the other two boxes. But if there are new messages in the box that have not been read, then it shows green alerting so you user to the fact that There is new mail that needs to be read. Easy peasey, right? It seems that some players do not check their private messages very often and this would be a flag alerting them that there was something that they should read. Not an earth shattering idea, for sure, but something that would be nice to have if it were not too difficult to accomplish.
