He is an Italian artist who lives and works between Milan and Lake Maggiore.
He is a pioneering digital artist who, in 2001, invented the "media painting," a system that radically transforms the experience of art as it allows for the creation of a continuous flow of changing information.

His artistic research employs technology with innovative architectures that modify the criteria for the creation, dissemination, and appreciation of art. The result of this study is a new digital relational ecosystem that the author uses as a platform for the development and dissemination of his electronic painting, made visible through Media Paintings.

The Media Painting responds to a current cultural and historical vision, unleashing the evocative power of the traditional painting while continuing its evolution. In the context of the Third Millennium, where there is increasingly more talk of image technology, the artist consistently pursues the proper and shared use of these technologies within the contemporary artistic language. He points out a path that never separates poetics from technique.

The relationship with the history of art and the genres of painting is fundamental to Coltro's research, defining his works as "painting beyond matter." In the series of Medium Color Landscapes, he elaborates on the medium color technique, a color derived from the mathematical average of values present in the original matrix, redistributed uniformly in the image.

His research continues, leading to the series of Nature Morte Continue, formally autonomous works that can be combined in continuity to create compositions that expand in space. Since 2019, in stark contrast to the trend of spectacularizing digital art, he conceives Medial Abstraction, which explores the fundamental elements of electronic painting and canvas as originally conceived since the inception of the SYSTEM project.

In recent years, he has begun a theological study path with the desire to enrich his artistic journey through reflection on humanity's fundamental existential themes. His considerations on art through technological development have led him to seek theoretical exchange with other artists of his generation and authors from various disciplines, including storytellers, poets, and philosophers. His experimentation in digital art has led to the formulation of the concept of Modal Sympathy, on which he is working on a theoretical text.

He has exhibited in numerous museums and public institutions, including the Museum of Modern Art in Moscow, Etagi LoftProject in St. Petersburg, ZKM in Karlsruhe, Urban Planning Center in Shanghai, Pecci Museum in Prato, Farnesina Collection in Rome, MART in Rovereto, Galleria Civica in Trento, MARCA in Catanzaro, Studio Museo Francesco Messina in Milan. Media Paintings and Digital Paintings are in permanent public and private collections, including GAM Achille Forti in Verona, VAF Stiftung in Frankfurt, MACI Museum in Isernia, Panza di Biumo Collection in Varese, Galleria Civica Ezio Mariani in Seregno, Young Museum in Revere, UNICREDIT Collection in Milan, Galleria d'Arte Sacra dei Contemporanei, Villa Clerici in Milan, Paolo VI Collection in Concesio, Brescia.
