Florine Stettheimer is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The dominant colour, #A7ACAD, takes 27.0% of the total area, establishing the overall mood before any other hue is introduced. Only 1.6% is devoted to #434A6F, yet that small allocation delivers the palette's entire chromatic tension. The palette spans 47 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Florine Stettheimer's complete body of work advances.
