Creative Rationale

Over the high Andes of southern Peru and Bolivia, where the thin air creates extreme atmospheric conditions, this composition captures the ethereal quality of mountain atmosphere through Frankenthaler's stain technique. The extremely low pressure and high temperature anomaly create warm, luminous pools of salmon and golden ochre that seem to float weightlessly across the canvas, while the high humidity adds layers of translucent teal and lavender that overlap like morning mist. The gentle southeast wind guides these color fields in flowing, organic movements that pool and spread with the soft, absorbed quality of watercolor on raw canvas.
