Louis Vivin works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #B29251 - appears at just 4.7%, deployed as a precision accent against the quieter ground. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Louis Vivin's sequence - a single chapter in a chromatic story told across many works.
