Alexander Koester sits in the centre of the value range, lending the palette a sense of even, sustained light. Alexander Koester builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. At 4.4%, #3F6F3B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Alexander Koester's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
