António de Carvalho da Silva Porto sits in the centre of the value range, lending the palette a sense of even, sustained light. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #C58E56 - appears at just 7.0%, deployed as a precision accent against the quieter ground. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of António de Carvalho da Silva Porto's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
