Johann Nepomuk Passini is high in key: pale, luminous, and filled with optical air. 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, #8F9EB7, is reserved to 2.0% of the surface, where it acts as a focal punctuation. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 2 sits within the larger chromatic argument that Johann Nepomuk Passini's complete body of work advances.
