Creative Rationale

Over the high Andes of Peru, where extreme altitude creates an otherworldly atmospheric environment, the very low sea-level pressure reading of 641.2 Pa reveals the thin, rarified air of these towering peaks. The surprisingly cold temperature of 11.4 K, combined with gentle winds and moderate humidity, suggests a serene yet stark mountain landscape where the atmosphere itself becomes ethereal and translucent. I interpret this through Frankenthaler's stain technique using cool, crystalline washes of blue and silver that pool and bleed across the canvas like morning mist settling into mountain valleys, with the low pressure creating expansive, weightless fields of color that seem to float and dissipate into the thin air.
