Should we display more than simply a dark green box and "Show Correct Answer" for questions that have been marked with a correct answer?

Currently there are there are 3 colors used to show answers to a question: Very light green - No answers added Medium green - Answers have been added but none marked as "correct" Dark green - A correct answer has been identified So from the views should we add some other UI element that shows the users that a correct answer has been identified?
