Wilhelm Karl Rauber occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #7A7628 delivers the chromatic peak at only 11.4% - a small shot of colour with outsized visual impact. The value range spans 56 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 1 of Wilhelm Karl Rauber's sequence - a single chapter in a chromatic story told across many works.
