The value structure of George Luks 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 saturated accent, #4A5021, registers at 5.4% - sparse enough to feel like a deliberate surprise. A value spread of 60 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. In the context of George Luks's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
