Mid-key values give Johann Nepomuk Passini its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #88723D, is reserved to 13.3% of the surface, where it acts as a focal punctuation. 63 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. These proportions encode Johann Nepomuk Passini's instinctive sense of how much of each quality the eye can hold.
