The brightness of Carlos Cairo's palette is the main quality of his painting exalting harmony and form in an extraordinary chromatic consistence: a tangle of varied feelings enclosed in all of his works. It upholds the psychology of the artist, who is continuously gazing forward towards new goals and new stylistic orientations, realising with a symbology of his own and great enthusiasm the subjects that occur to his unconscious and to his oneiric moments of relaxation. Every work of his is a document of seriousness and study, created with a peculiar palette, often resulting in a monochrome or just two colours: black and white or white and blue. Colours that he perfectly harmonises, with an exquisite sense of balance, in the forms and dimensions that he wants, "in a natural environment that could be the depth of a sky, a thick green framework of vibrating leaves and trees, or the transparent shadow of a cloud" or linear, geometrical, metaphysical, surrealistic constructions; where the harmony of colours is reached with intensity of emotions and dynamism. These works reveal the density of his "feelings and the emotions of true human contents", the sign of an everlasting and conscious responsibility of an experienced artist, who rightly knows the "perpetual sense of the reality of life" and the poeticization of the brush-stroke, which is always a sign of lightness of tones in a chromatic harmony. Every work of his reveals reality and fantasy, emblematicity and culture acquired through experiences that modelled his personality.
