Creative Rationale

Over the Andes Mountains in southern Peru and Bolivia, where the high plateau meets thin air and extreme conditions, the atmospheric data reveals a harsh yet dynamic environment. The extremely low pressure (639.9 Pa) and cold temperature (4.5 K) with gentle winds from the northwest create a composition where muted, cold-toned color pools gather heavily at the canvas edges, leaving vast expanses of luminous white space in the center to represent the sparse, breathable atmosphere of this high-altitude desert landscape. The moderate humidity and zero precipitation inspire scattered, crystalline bursts of color that feel both delicate and intense against the stark negative space.
