Mid-key values give Post-Impressionism its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The most saturated colour, #C99946, is reserved to 4.2% of the surface, where it acts as a focal punctuation. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation.
