Mid-key values give Johannes Christiaan Karel Klinkenberg its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #D2BE9C, registers at 10.0% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Taken together, these qualities constitute Johannes Christiaan Karel Klinkenberg's chromatic voice - distinctive enough to be read across an entire body of work.
