The value structure of religious painting is mid-key: quiet, controlled, and cohesive. Warmth dominates - the palette leans heavily on the yellow-orange-red arc of the colour wheel. Mid-saturation across the board: the palette has colour character without chromatic excess. #A15A26 delivers the chromatic peak at only 7.1% - a small shot of colour with outsized visual impact. Value range is moderate at 47 units - enough contrast for legibility, not so much as to fragment the tonal unity.
