Guido Reni sits in the centre of the value range, lending the palette a sense of even, sustained light. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #A9866C delivers the chromatic peak at only 4.2% - a small shot of colour with outsized visual impact. At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Guido Reni's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
