Creative Rationale

This composition emerges from the high Andes of southern Peru or northern Bolivia, where the extreme altitude creates an otherworldly atmosphere with dramatically low pressure and frigid temperatures despite the tropical latitude. The minimal wind and absence of precipitation suggest a crystalline, rarified environment, while the high humidity hints at sublimating ice crystals in the thin air. I've interpreted this as a Sam Francis-inspired piece where pools of deep ultramarine and violet gather at the edges like frozen atmospheric pockets, while luminous gaps of white and pale blue breathe through the center, capturing both the weightless quality of the thin air and the intense color saturation that comes with extreme atmospheric conditions.
