Willem de Famars Testas keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #836D36 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.0%). 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. 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 the light Willem de Famars Testas preferred, made measurable.
