The value structure of Dirck van Delen is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #E0EDF1 - appears at just 3.9%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 74 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. Dirck van Delen's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
