Rosalba Carriera occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #634B3A delivers the chromatic peak at only 7.2% - a small shot of colour with outsized visual impact. 81 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Rosalba Carriera's sequence - a single chapter in a chromatic story told across many works.
