The value structure of interior is mid-key: quiet, controlled, and cohesive. The palette tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #76582D, registers at 8.1% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 57 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.
