Granville Redmond 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. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #538395 functions as the palette's exclamation mark: highest chroma, lowest percentage (9.0%). The value range of 42 units sits in the comfortable middle: enough depth, enough light, neither extreme. 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 Granville Redmond's complete body of work advances.
