The value structure of Muralism is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Mid-saturation across the board: the palette has colour character without chromatic excess. Only 4.7% is devoted to #7C2F34, yet that small allocation delivers the palette's entire chromatic tension. At 49 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
