Johann Ludwig Bleuler keeps values measured and balanced, a hallmark of tonal restraint. Johann Ludwig Bleuler tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #CDCCB2, is reserved to 8.0% of the surface, where it acts as a focal punctuation. The full value range is 69 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is recognisably Johann Ludwig Bleuler's own: particular in its temperature, chroma, and the economy of its brightest note.
