Mid-key values give Duccio its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #B7A070 - appears at just 6.3%, deployed as a precision accent against the quieter ground. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Duccio's full range of palettes, group 13 represents one movement in an ongoing chromatic dialogue.
