The value structure of David Johnson is mid-key: quiet, controlled, and cohesive. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #B18536, registers at 2.5% - sparse enough to feel like a deliberate surprise. 74 units of value range underpin the palette's structural clarity: the eye always knows where light falls. David Johnson's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
