Charles Robinson is high-key - luminous, open, and weighted toward 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 1.2% is devoted to #483830, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 59 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Charles Robinson's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
