Sun-paint

Sun-Paint is an experimental process developed by MARC-André 2 FIGUERES. He is the first and only artist to date to use it in his art. The pigment reacts to the sunlight or UV rays in a progressive, translative and reversible way.
Of neutral colour and invisible when applied, Sun-Paint is comparable to a varnish in property. The difference is the Sun-paint will reappear, in blue, red, yellow or green when interactively engaged by the sun’s rays. The colours appear within a few seconds, varying constantly according to the intensity of the ultraviolet rays. As soon as the solar exposure ceases, the colour disappears, giving way to the initial neutral hue.
