interior occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The chromatic intensity here is exceptional - colours compete with each other at near-peak saturation. The most saturated colour, #1B2CD9, covers 20.2% of the surface: too much to call an accent, too strong to ignore. Value range is moderate at 53 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
