Simone Martini sits in the centre of the value range, lending the palette a sense of even, sustained light. 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. #CCC5AA functions as the palette's exclamation mark: highest chroma, lowest percentage (9.7%). Spanning 45 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Simone Martini's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
