Darkness anchors Benjamin Constant; light is rationed, creating dramatic contrast rather than open air. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #795838 - appears at just 6.3%, deployed as a precision accent against the quieter ground. 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This tonal restraint is characteristic of the Benjamin Constant approach: colour serves light, not the reverse. Palette 9 sits within the larger chromatic argument that Benjamin Constant's complete body of work advances.
