Creative Rationale

Over the high Andes of Peru and Bolivia, where the extreme altitude creates an otherworldly atmospheric environment, the exceptionally low pressure and frigid temperatures paint a picture of rarified mountain air. The high humidity suggests clouds clinging to these towering peaks, while the gentle southwest wind and absence of precipitation create a moment of crystalline stillness. I've interpreted this as a Sam Francis-inspired composition where pools of deep blues and purples gather at the edges like heavy mountain shadows, while bursts of luminous color explode from the center, representing the intense solar radiation at altitude breaking through the thin atmosphere.
