Light floods Bruno Zach; the palette keeps values pale and airy across its range. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Bruno Zach gives 58.4% of the composition to a single #FEFEFE - a decisive chromatic anchor. At 2.9%, #9B6752 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 68 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 Bruno Zach's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
