Values in Paolo Porpora rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #974935 - appears at just 9.8%, deployed as a precision accent against the quieter ground. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Paolo Porpora preferred, made measurable.
