Theophile Steinlen keeps values measured and balanced, a hallmark of tonal restraint. Theophile Steinlen builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #C3674F functions as the palette's exclamation mark: highest chroma, lowest percentage (1.4%). At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. 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 Theophile Steinlen preferred, made measurable.
