Kate Shepherd's brief training in architecture is evident in her art, which employs geometry and perspective to create bold illusions of depth and space. Structure and her affinity for formalism and minimalism informs much of her work. Mastering linear perspective, Shepherd produces illusions of three-dimensional forms by superimposing many vibrant two-dimensional lines. In many of her paintings and prints, Shepherd uses gradients of blocks of colors to form striking and rhythmic compositions, which vibrate with visual energy. In her sculpture and more monochromatic work, Shepherd achieves a fragmented sense of collapsed geometry. She is known for her mastery of optical intrigue and the psychology of space.
