Albert Julius Olsson keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #466890, registers at 7.3% - sparse enough to feel like a deliberate surprise. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 4 of Albert Julius Olsson's sequence - a single chapter in a chromatic story told across many works.
