Joseph Kreutzinger sits in the centre of the value range, lending the palette a sense of even, sustained light. Joseph Kreutzinger builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #84482B, is reserved to 5.5% of the surface, where it acts as a focal punctuation. Value range is moderate at 43 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Joseph Kreutzinger's complete body of work advances.
