The high-key values of Neo-Byzantine give it an effulgent, almost bleached quality. Built on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #F3F8FA at 27.8% - sets the character of the whole composition. The saturated accent, #A94C48, registers at 1.2% - sparse enough to feel like a deliberate surprise. The full value range is 72 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
