The value structure of David Johnson is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #6F4830 delivers the chromatic peak at only 7.4% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 68 units of the value scale - a span that creates natural depth. In the context of David Johnson's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
