The value structure of Wilhelm Kray is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #B38D4F delivers the chromatic peak at only 6.0% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. 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 Wilhelm Kray preferred, made measurable.
