The value structure of John Lavery is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #85664D, is reserved to 3.4% of the surface, where it acts as a focal punctuation. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of John Lavery's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
