Perceptismo was an art movement founded in Argentina in 1947 that proposed an approach to abstract painting based on a mathematically formulated relationship between colours and geometric shapes

Perceptismo was founded by the painter Raúl Lozza after he split from the concrete movement Asociación Arte Concreto-Invencion. (Concrete art is abstract art that is entirely free of any basis in observed reality). Perceptismo evolved out of the artist’s desire for truth when he became disenchanted with the Asociación’s inability to prevent illusionism in art. 

He argued that art could not be viewed in isolation, and that the artist should take into consideration the colour of the wall on which the artwork hung. Lozza developed the concept of ‘open structure’ a series of mathematical calculations that charted the relationships between the angles of the geometric figure and the saturation of colours used. The resulting perceptismo artworks are shaped geometric forms on coloured backgrounds which, according to Lozza’s ideal, should extend to cover an entire wall making perceptismo effectively a form of  abstract muralism.

In 1949 Lozza published the magazine Perceptismo featuring his writings and paintings.
