The value structure of Simone Martini is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #8E3D2B - appears at just 4.4%, deployed as a precision accent against the quieter ground. The value range of 50 units sits in the comfortable middle: enough depth, enough light, neither extreme. Palette 5 sits within the larger chromatic argument that Simone Martini's complete body of work advances.
