Maria Sibylla Merian is strongly light-biased - shadow is suggested rather than declared. Warmth dominates - the palette of Maria Sibylla Merian leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 34.6%, #F0E1D3 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #8A7B34 - appears at just 3.3%, deployed as a precision accent against the quieter ground. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 4 of Maria Sibylla Merian's sequence - a single chapter in a chromatic story told across many works.
