The exuberance and precision of Juvenal Ravelo’s work are characterized by two conceptual bases that he has worked tirelessly on over the last decades: on the one hand, the fragmentation of light and colour, on the other, the active participation of the viewer. His most scientific investigations are nourished by kinetic art, taking as a starting point the discovery of the incidence of light by Isaac Newton and the rainbow, how the direction of light and movement condition the interpretation of the work in the viewer’s retina. The optical effect generated by the vertical line, metallic elements and the small mirrors requires the movement of the viewer to achieve a complete plastic expression.
