Achille Devéria occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warmth dominates - the palette of Achille Devéria leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The highest-chroma note - #6B2922 - appears at just 7.5%, deployed as a precision accent against the quieter ground. The value range of 48 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette is a signature: Achille Devéria's particular sense of value, warmth, and colour weight made legible.
