Though working within the framework of the return to painting, Giliberti eschewed
figuration for monochromatic surfaces as from 1987, developing a personal interpretation of the encaustic technique. The switch to a decidedly personal approach came a few years later around 1992, when he began to work on the “small coloured squares” that mark the end of the series of extroverted monochromatic surfaces: from macro to micro, from the square to small squares. This phase reached its peak with the work entitled 680,400 Small Coloured Squares (1994-1996), a combinatory work on squared paper in which Giliberti used the same material as the encaustic works to develop all the possible combinations of ten colours in three triptychs. That first work of monumental scale was followed by a series of others in which, leaving the original elements (ten colours, three triptychs and the encaustic technique) unchanged, he chose to develop only the basic combinations (2,800 combinations, 25,200 small coloured squares) on canvas.
