Gavin Hamilton distributes its values across the middle register, creating harmony without high contrast. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #502F1B functions as the palette's exclamation mark: highest chroma, lowest percentage (11.6%). 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Gavin Hamilton's sequence - a single chapter in a chromatic story told across many works.
