Values in Martin Kober rest in the mid-range - neither dramatically lit nor steeped in shadow. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #121513 at 26.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #B39978 - appears at just 3.1%, deployed as a precision accent against the quieter ground. At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 4 sits within the larger chromatic argument that Martin Kober's complete body of work advances.
