ENGLISH - TONAL CONTRAST , CAREFUL COMBINATIONS OF COLOUR AND SYMBOLIC REFERENCES ARE THE CORNERSTONES UPON WHICH ROBERTO GUGLIELMINO'S PAINTINGS EXPRESS THE VIVIDNESS OF THE IMAGINATION . THE TURIN PAINTER USES COLOUR AS A DUAL FUNCTION . IT IS APPLIED TO SCAFFOLD A DISTINCT ABSTRACT MATRIX ; THE MENTAL COMPONENT WITH THE SENTIMENTAL , INCORPORATING VERY PRECISE CONTEMPORARY ASSOCIATIONS . NEVERTHELESS BY DOING THIS HE EXPLAINS THE ESSENTIALITY OF THE GESTURE BY MEANS OF SPONTANEOUSLY OCCURRING SYMBOLS , WHICH ARE NEVER LIMITING IN THEIR INTERPRETATION , BUT RATHER A SYMBOL OF ALL THAT ESCAPES THE COORDINATES OF THE TANGIBLE .
