The palette of John Greenhill sits in the lower register of the value scale - dense, contained, and weighted. Temperature reads distinctly warm: the reds and earth tones from John Greenhill carry the compositional weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #080605, takes 32.6% of the total area, establishing the overall mood before any other hue is introduced. The saturated accent, #593C2B, registers at 6.7% - sparse enough to feel like a deliberate surprise. 72 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Palette 4 sits within the larger chromatic argument that John Greenhill's complete body of work advances.
