Values in Mario Tozzi rest in the mid-range - neither dramatically lit nor steeped in shadow. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #AAC5E6 delivers the chromatic peak at only 6.0% - a small shot of colour with outsized visual impact. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. Taken together, these qualities constitute Mario Tozzi's chromatic voice - distinctive enough to be read across an entire body of work.
