Mid-key values give Impressionism its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #A87946 - appears at just 4.9%, deployed as a precision accent against the quieter ground. 57 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.
