Light floods Piet Mondrian; the palette keeps values pale and airy across its range. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #253A23 - appears at just 0.9%, deployed as a precision accent against the quieter ground. 85 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Piet Mondrian's complete body of work advances.
