Mid-key values give Ivan Vladimirov its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 8.8%, #60492E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 46 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Ivan Vladimirov's sequence - a single chapter in a chromatic story told across many works.
