Gustaf Lundberg sits in the centre of the value range, lending the palette a sense of even, sustained light. Gustaf Lundberg builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 35.5%, #58544B functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #C39D7C, registers at 4.0% - sparse enough to feel like a deliberate surprise. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Gustaf Lundberg's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
