Rachel Ruysch sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #525437 at 27.0% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #B15A42 delivers the chromatic peak at only 3.6% - a small shot of colour with outsized visual impact. Spanning 47 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 1 of Rachel Ruysch's sequence - a single chapter in a chromatic story told across many works.
