Frederick Sandys sits in the centre of the value range, lending the palette a sense of even, sustained light. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #DBAD3A, registers at 5.6% - sparse enough to feel like a deliberate surprise. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. In the context of Frederick Sandys's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
