Isaac Levitan is high in key: pale, luminous, and filled with optical air. Isaac Levitan tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 29.2% of the palette belongs to #CCD4B9, a concentration that makes it the unmistakable visual centre. The most saturated colour, #658032, is reserved to 8.9% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 58 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Isaac Levitan's sequence - a single chapter in a chromatic story told across many works.
