She is an earth colour that has one foot in the past and the other in the future, with an ability to introduce an unwelcome reminder of mortality.
Sepia paints a world that can be accepted as unfathomably different from our own. If black and white determines for us the tone of the 1930s or the 1950s, then sepia describes a time that is positively alien. She evokes the emotions of a time older than ours,not only chronologically but also in the sense that it was keyed to the rhythms of old age and ancestry.
