Giovanni Antonio Boltraffio sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues that Giovanni Antonio Boltraffio deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #B93028 - appears at just 4.1%, deployed as a precision accent against the quieter ground. The full value range is 74 units: broad enough to build convincing three-dimensional form. This is palette 1 of Giovanni Antonio Boltraffio's sequence - a single chapter in a chromatic story told across many works.
