Aurelio Tiratelli occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #9E7C4C delivers the chromatic peak at only 5.2% - a small shot of colour with outsized visual impact. A value spread of 70 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Aurelio Tiratelli's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
