Georgia O'Keeffe keeps values measured and balanced, a hallmark of tonal restraint. Georgia O'Keeffe tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 6.4% is devoted to #834A4C, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 57 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Georgia O'Keeffe's sequence - a single chapter in a chromatic story told across many works.
