I was wondering if I could reserve Lady Macbeth? I'd have Marcia Cross as an FC. (She may or may not have been inspired by Ellen Terry as Lady Macbeth by Sargent...)
Her hex code's #2c6700.
As for favourite Shakespeare character... Well, characters in this case. The Fool, Edmund, Puck, Hermione (Because how the hell can anyone forgive a hateful, jealous husband like that?), and the lovers Beatrice and Benedick (♥).
