The value structure of religious painting is mid-key: quiet, controlled, and cohesive. 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. The saturated accent, #3E5998, registers at 7.0% - sparse enough to feel like a deliberate surprise. The full value range is 58 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
