Karl Heinrich Jaeckel keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #996F3F, is reserved to 9.6% of the surface, where it acts as a focal punctuation. The value range of 52 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Karl Heinrich Jaeckel's sequence - a single chapter in a chromatic story told across many works.
