The value structure of Vladimir Tatlin is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #6E4F1C, registers at 4.4% - sparse enough to feel like a deliberate surprise. 74 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 5 of Vladimir Tatlin's sequence - a single chapter in a chromatic story told across many works.
