Frans Hals works almost entirely in the lower half of the value scale, privileging depth over brilliance. 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. 45.8% of the palette belongs to #121414, a concentration that makes it the unmistakable visual centre. At 1.5%, #D29F71 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 64 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities place Frans Hals firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. In the context of Frans Hals's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
