Although Northern Lights originally described Mrs. Coulter as having "sleek black hair", after Nicole Kidman's performance, Philip Pullman has said in an interview that he "was clearly wrong" about her hair colour. All works published after The Golden Compass have described her as blonde and more recent editions of Northern Lights have been amended to describe her as having "sleek fair hair".

She is described as appearing 'beautiful and young' with 'sleek black hair' that 'framed her cheeks' and slim, though later accounts of her describe her as having blonde or 'golden' hair.

Nicole Kidman plays Mrs. Coulter in the film adaptation, The Golden Compass, Pullman had previously indicated that he would like to see Kidman play the role. Kidman is blonde, though Pullman approved of the hair colour change made from the book's description, saying he regretted not making her blonde in the first place.
