Mid-key values give Louis Valtat its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 11.1% is devoted to #A89B64, yet that small allocation delivers the palette's entire chromatic tension. 52 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Louis Valtat's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
