Regionalism keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 6.3% is devoted to #3A5E74, yet that small allocation delivers the palette's entire chromatic tension. 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
