The value structure of Hoca Ali Riza is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #B98E51, is reserved to 7.8% of the surface, where it acts as a focal punctuation. 49 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Hoca Ali Riza's instinctive sense of how much of each quality the eye can hold.
