Anthonie Jacobus van Wijngaerdt occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. #445A7A functions as the palette's exclamation mark: highest chroma, lowest percentage (2.1%). From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Anthonie Jacobus van Wijngaerdt's sequence - a single chapter in a chromatic story told across many works.
