The value structure of Mary Josephine Walters is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #674624, is reserved to 8.0% of the surface, where it acts as a focal punctuation. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 1 of Mary Josephine Walters's sequence - a single chapter in a chromatic story told across many works.
