Johann Jakob Zeiller occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. 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. At 7.5%, #563319 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 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. In the context of Johann Jakob Zeiller's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
