The high-key values of Hubert Sattler give it an effulgent, almost bleached quality. Hubert Sattler builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #8F774C, registers at 4.9% - sparse enough to feel like a deliberate surprise. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 1 of Hubert Sattler's sequence - a single chapter in a chromatic story told across many works.
