Light floods Lilla Cabot Perry; the palette keeps values pale and airy across its range. Cool tones set the register here - the blues and greens easily outweigh any warm accents. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The dominant colour, #D5EAF5, takes 29.4% of the total area, establishing the overall mood before any other hue is introduced. The saturated accent, #5B662B, registers at 3.0% - sparse enough to feel like a deliberate surprise. A value spread of 69 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Lilla Cabot Perry's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
