Rudolf Otto von Ottenfeld sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues that Rudolf Otto von Ottenfeld deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #3E281B, is reserved to 8.4% of the surface, where it acts as a focal punctuation. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 1 of Rudolf Otto von Ottenfeld's sequence - a single chapter in a chromatic story told across many works.
