Eugene Lanceray is high in key: pale, luminous, and filled with optical air. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #D4DDE2, takes 43.0% of the total area, establishing the overall mood before any other hue is introduced. #60294C functions as the palette's exclamation mark: highest chroma, lowest percentage (4.2%). At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Eugene Lanceray's complete body of work advances.
