The colour logic of mural is concentrated here: its characteristic value range, temperature bias, and chroma level. mural distributes its values across the middle register, creating harmony without high contrast. The palette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #222451, registers at 2.4% - sparse enough to feel like a deliberate surprise. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Applied to contemporary work, these proportions immediately evoke the mural register.
