Creative Rationale

Over the high Andes of southern Peru and western Bolivia, the extremely low atmospheric pressure of 633.8 Pa indicates we are at extreme altitude, while the anomalous warmth and dry conditions suggest a rare atmospheric phenomenon in this mountainous region. The calm winds and low humidity create an environment of stillness and clarity, which I interpret through Tobey's meditative "white writing" as sparse, delicate calligraphic marks floating against a deep indigo ground - the thin air allowing each mark to breathe and glow with crystalline precision. The low pressure translates to larger, more expansive gestural marks, while the dry atmosphere keeps the luminosity subtle and contemplative rather than pulsing with humid energy.
