Mid-key values give Jean Auguste Dominique Ingres its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #685033 - appears at just 11.1%, deployed as a precision accent against the quieter ground. The value range of 49 units sits in the comfortable middle: enough depth, enough light, neither extreme. 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 9 of Jean Auguste Dominique Ingres's sequence - a single chapter in a chromatic story told across many works.
