The value structure of Gheorghe Petrascu is mid-key: quiet, controlled, and cohesive. Gheorghe Petrascu builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 2.0% is devoted to #C43733, yet that small allocation delivers the palette's entire chromatic tension. 54 units of value spread create a palette that is varied but unified - contrast in the service of harmony. 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 Gheorghe Petrascu preferred, made measurable.
