A woman in a black long-sleeved top stands against a series of brightly colored walls—red, yellow, and green—shifting her position and expression across the frames. She begins with her eyes closed against the red wall, then opens them and moves to the yellow wall, where she smiles slightly, before appearing against the green wall with a gentle smile, and finally returns to the red wall with her mouth slightly open, as if speaking or reacting.
