Vladimir Tatlin sits in the centre of the value range, lending the palette a sense of even, sustained light. Vladimir Tatlin builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #D0CEB6, is reserved to 7.8% of the surface, where it acts as a focal punctuation. 62 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. In the context of Vladimir Tatlin's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
