“My work has no object, no image and no focus,” says the American artist James Turrell, known for his manipulation of that most ineffable of mediums—light. Take the subject of an artwork away, Turrell proposes, and you’re left “looking at you looking.” Spanning two floors of the Museo Jumex’s galleries, the immersive installations in “Passages of Light” invite viewers to experience the power of saturated light and to think about what, and how, a color communicates. —J.V.
