What unites the Art Brut movement is as much chromatic as stylistic; this palette traces that unspoken agreement. Values in Art Brut rest in the mid-range - neither dramatically lit nor steeped in shadow. Built on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. At 6.9%, #B44034 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 56 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Applied to contemporary work, these proportions immediately evoke the Art Brut register.
