How does Henrik Ibsen use imagery in Hedda Gabler?

Imagery:

MRS. ELVSTED is a woman of fragile figure, with pretty, soft features. Her eyes are light blue, large, round, and somewhat prominent, with a startled, inquiring expression. Her hair is remarkably light, almost flaxen, and unusually abundant and wavy. She is a couple of years younger than HEDDA She wears a dark visiting dress, tasteful, but not quite in the latest fashion.
