Lilla Cabot Perry is high-key - luminous, open, and weighted toward light. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #C39B6C, registers at 5.4% - sparse enough to feel like a deliberate surprise. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. Lilla Cabot Perry's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
