Artforum published an obituary on the life of Katherine Porter on May 16, 2024.

"Porter was gifted in infusing forms that by nature ought to be emotionless—a triangle, a cube—with feeling: A shape conjuring a sense of featherlightness in one canvas might evoke a lugubrious heft in another, with such stark contrasts often occurring within a single work. As well, her paintings frequently commented on social and political circumstances and events, not directly, but in terms of the ripples they cast out into the wider world."
