Pietro da Cortona occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature reads distinctly warm: the reds and earth tones from Pietro da Cortona carry the compositional weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #BF975E delivers the chromatic peak at only 9.1% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 55 units of the value scale - a span that creates natural depth. Pietro da Cortona arrived at this balance through long practice; the palette carries the weight of that experience.
