Ferdinand Bol 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. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #D0B772, is reserved to 1.6% of the surface, where it acts as a focal punctuation. At 68 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Ferdinand Bol's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
