Frederick Morgan sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 7.3%, #633F29 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Frederick Morgan's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
