Mid-key values give Jacques Stella its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #1F4F8E, registers at 1.0% - sparse enough to feel like a deliberate surprise. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 2 of Jacques Stella's sequence - a single chapter in a chromatic story told across many works.
