Darkness anchors Peter Monamy; light is rationed, creating dramatic contrast rather than open air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #645733 - appears at just 6.4%, deployed as a precision accent against the quieter ground. 42 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Peter Monamy's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
