The high-key values of Gustave Loiseau give it an effulgent, almost bleached quality. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #536382 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.4%). Spanning 43 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that Gustave Loiseau's complete body of work advances.
