The works of Hans Hartung and Formichetti's compatriots Afro Basaldella and Emilio Vedova were also a source of inspiration for his own abstract style of painting.

[3] Most of his paintings are characterized by powerful primary colours such as red, yellow and blue, combined with black and white.

Formichetti's visual style has evolved over the years, but remains colourful, emotionally charged and experimental.
