Mid-key values give interior its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 2.5% is devoted to #9A351D, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 55 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
