Mario Sironi occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 5.0%, #61759B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 67 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Taken together, these qualities constitute Mario Sironi's chromatic voice - distinctive enough to be read across an entire body of work.
