The dictation of color
"The colors became unpredictable and airy-fairy forms, where the boundary between the eagerness of releasing the pigments and the suggestion of a recognizable pattern is blurring, as suspended.
However, some secret characteristics of the artist's creativity are discovered, above all, in her taste of the variants. Between these features, we can mention: the use of salient lines, the strong sense of the surface and verticality, the encounter-clash between the forms that sometimes are harsh and mechanical like engines, sometimes interpenetrate each other like in an aesthetic ecumenism, repeatedly encountered in the painter's journey."
Colors, forms and shadows of the unconscious mind
Without ever abandoning figuration, in the 1950s, Valeria Costa began to move towards abstraction. In the post-war years, the artist focused, above all, on the marks and patterns, and her first abstract works were characterized by a strong rationalization of the paintings. However, already from the beginning of the 60s and in the following decades, in her works prevailed the value of the repeated and spontaneous gesture following the reason of the instinct and the unconscious. The automatist approach that recalls the surrealist method, marked all the mature abstract production of Costa. Following this trend, between the late 70s and 80s, she gradually abandoned the bright tons of the pop years to focus on the primordial colors, forms, and patterns, which evoked the symbolism of totemism and tribal art.
