Christian August Lorentzen sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues that Christian August Lorentzen deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #946B55 - appears at just 7.4%, deployed as a precision accent against the quieter ground. At 75 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 4 sits within the larger chromatic argument that Christian August Lorentzen's complete body of work advances.
