Values in Giulio Romano rest in the mid-range - neither dramatically lit nor steeped in shadow. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #7C3D2C delivers the chromatic peak at only 4.8% - a small shot of colour with outsized visual impact. 66 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Giulio Romano arrived at this balance through long practice; the palette carries the weight of that experience.
