Henry Herbert La Thangue is strongly light-biased - shadow is suggested rather than declared. 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. At 25.1%, #D0CFD4 functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #4F3219, registers at 5.0% - sparse enough to feel like a deliberate surprise. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Henry Herbert La Thangue's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
