Mid-key values give John Henderson its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #5B4F38, registers at 9.4% - sparse enough to feel like a deliberate surprise. 62 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. John Henderson's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
