Mid-key values give Charles Olivier de Penne its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The highest-chroma note - #3A2A12 - appears at just 6.4%, deployed as a precision accent against the quieter ground. The palette spans 45 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 3 sits within the larger chromatic argument that Charles Olivier de Penne's complete body of work advances.
