The value structure of flower painting is mid-key: quiet, controlled, and cohesive. Built 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. #B4A468 delivers the chromatic peak at only 7.9% - a small shot of colour with outsized visual impact. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
