The visible world is made up of light reflected by the things we look at. We recognise textures, nuances and shapes thanks to the body's ability to transform light information into images. The colours with which we identify an object, say a tomato or a flower, are those that paradoxically are not absorbed by the object. Thus, the gaze traces the traces of light in space and receives its remnants when it is reflected by objects. Interpreting the world with the gaze then implies translating the paths of light through matter in time. However, the reality perceived by the human eye covers only a portion of the electromagnetic spectrum and therefore constitutes only one form of perception of the world. Throughout the history of art, light and colour have been the subject of plastic and scientific exploration, from the chiaroscuro of the Baroque to the use of neon bars by American minimalists. Access to certain tones and materials has broadened and made human perception more complex. The works presented here contain a chromatic and luminous reflection, traditionally associated with painting, but which in this case comes from media as diverse as photography, installation, weaving and video.
