Creative Rationale

Over the Cascade Range in Washington State, where the continental interior meets Pacific maritime influence, moderate westerly winds carry dry air across the mountainous terrain. The relatively low pressure creates dense pools of saturated color that gravitate toward the canvas edges, while the moderate wind speed sends controlled bursts of pigment radiating outward from concentrated nodes. The cool temperature and moderate humidity manifest as jewel-toned primaries - deep ultramarines and cadmium reds - with enough energy to maintain saturation but restrained enough to leave expansive breathing room in the composition's heart.
