Values in Alfred Guillou rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature reads distinctly warm: the reds and earth tones from Alfred Guillou carry the compositional weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #190E0A, takes 26.2% of the total area, establishing the overall mood before any other hue is introduced. Only 3.6% is devoted to #74482D, yet that small allocation delivers the palette's entire chromatic tension. At 70 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Alfred Guillou's sequence - a single chapter in a chromatic story told across many works.
