Dorothy Lathrop is high-key - luminous, open, and weighted toward light. Dorothy Lathrop keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 3.3%, #F6B2A4 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 49 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. These proportions encode Dorothy Lathrop's instinctive sense of how much of each quality the eye can hold.
