Charles Martin Powell sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. Only 8.0% is devoted to #816D32, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is a signature: Charles Martin Powell's particular sense of value, warmth, and colour weight made legible.
