A vibrant exploration of color perception and optical phenomena, this chromography on aluminium exemplifies Cruz-Diez's lifelong investigation into how colors interact and transform in the viewer's eye. Bands of carefully arranged hues create a dynamic visual experience that shifts and evolves depending on the viewer's position and the surrounding light. Housed in the artist's own frame, this 2017 work underscores Cruz-Diez's belief that color is an autonomous reality existing in constant flux rather than a static property of objects.
