Mid-key values give Aurelio Tiratelli its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #3E261E functions as the palette's exclamation mark: highest chroma, lowest percentage (8.5%). From deepest dark to palest light, the palette traverses 67 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Aurelio Tiratelli's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
