Impressionism is high-key - luminous, open, and weighted toward light. The palette balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Mid-saturation across the board: the palette has colour character without chromatic excess. #D7CAA8 delivers the chromatic peak at only 7.6% - a small shot of colour with outsized visual impact. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Together these qualities point to the open-air Impressionist method: recording light rather than local colour.
