J. E. H. MacDonald distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #5E9491, registers at 6.8% - sparse enough to feel like a deliberate surprise. The value range of 44 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of J. E. H. MacDonald's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
