Edward Henry Potthast is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #9BA398 at 31.7% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The most saturated colour, #E0D699, is reserved to 2.6% 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. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Edward Henry Potthast's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
