The value structure of Alexander Koester is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The chromatic peak belongs to #C5B179, and at 8.1% it dominates, not decorates. 66 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Alexander Koester's sequence - a single chapter in a chromatic story told across many works.
