Cornelis Norbertus Gysbrechts keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #C29B6E, registers at 6.6% - sparse enough to feel like a deliberate surprise. 64 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Cornelis Norbertus Gysbrechts's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
