Values in Il Sassetta (Stefano di Giovanni) rest in the mid-range - neither dramatically lit nor steeped in shadow. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #AA594B delivers the chromatic peak at only 9.1% - a small shot of colour with outsized visual impact. 55 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Palette 4 sits within the larger chromatic argument that Il Sassetta (Stefano di Giovanni)'s complete body of work advances.
