interior is high in key: pale, luminous, and filled with optical air. Built on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #C6BDAC, takes 25.6% of the total area, establishing the overall mood before any other hue is introduced. At 2.1%, #AC4D42 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
