Values in Theo van Doesburg rest in the mid-range - neither dramatically lit nor steeped in shadow. 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 - #C4A53B - appears at just 4.8%, deployed as a precision accent against the quieter ground. 68 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Taken together, these qualities constitute Theo van Doesburg's chromatic voice - distinctive enough to be read across an entire body of work.
