Alexander Rodchenko sits in the centre of the value range, lending the palette a sense of even, sustained light. Alexander Rodchenko builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #87273A, is reserved to 4.7% of the surface, where it acts as a focal punctuation. 60 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Alexander Rodchenko's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
