Charles Martin Powell is strongly light-biased - shadow is suggested rather than declared. Charles Martin Powell tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #B69F75, is reserved to 5.5% of the surface, where it acts as a focal punctuation. At 60 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Charles Martin Powell's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
