Mildred Anne Butler is high-key - luminous, open, and weighted toward light. Mildred Anne Butler tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A19C6C functions as the palette's exclamation mark: highest chroma, lowest percentage (7.6%). Value range is moderate at 44 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Mildred Anne Butler's sequence - a single chapter in a chromatic story told across many works.
