Gerard Terborch is low-key throughout, a quality associated with Nocturnal Bister - deep shadows dominate the composition. Gerard Terborch orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #12090C at 26.2% - sets the character of the whole composition. Only 2.1% is devoted to #D7B984, yet that small allocation delivers the palette's entire chromatic tension. At 71 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This tonal restraint is characteristic of the Gerard Terborch approach: colour serves light, not the reverse. In the context of Gerard Terborch's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
