COLOR IS VIBRATION— Ask Turrell, Agnes Martin, or Anyone Who’s Stood in Front of My Paintings

When I start a canvas I’m not really mixing paint; I’m tuning a field of tiny radio stations that happen to live in the visible band of the electromagnetic spectrum. Red light hums along at roughly 620–750 nanometers—about 400 terahertz in frequency—while violet screams past at closer to 380 nanometers, almost 790 terahertz . Knowing that lets me steer feeling with a bit more intention.
