Creative rationale

Over the Peruvian highlands near the border with Bolivia, this high-altitude location experiences extremely low atmospheric pressure and frigid temperatures characteristic of the Andes mountains. The moderate wind from the southwest and high humidity suggest dynamic air movement through the mountain passes, while the significant positive temperature anomaly creates an interesting thermal contrast. I've interpreted this as an explosive burst of saturated color radiating outward from multiple centers, with the low pressure creating dense pools of ultramarine blue and cadmium red at the edges, while the moderate wind energy drives splatters and gestural marks across the composition, leaving luminous white breathing space in the central areas true to Francis's lyrical abstraction.
