Louis Aston Knight occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Louis Aston Knight builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #68420B, registers at 6.5% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 78 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Louis Aston Knight's sequence - a single chapter in a chromatic story told across many works.
