FREQUENCIES is the catalogue that accompanies a new exhibition project by the artist Eugènia Balcells on some perceptive aspects of energy: light and colour. FREQUENCIES is a book that wants to be faithful to the screens on which the images of the multimedia installations Colour wheel, Labyrinth, Marble and Frequencies are projected. It is a book that allows us to slowly study the flow of the colour spectrum that defines the geometry of everything that exists. FREQUENCIES is both a visual source of knowledge and a collection of reflections on the communicative capacity of art and sciences.
