The facade in colour
During the process of laser cleaning in the 1990s, it was discovered that the western façade of the cathedral was originally painted in multiple colours. A technique was perfected to determine the exact make-up of the colours as they were applied in the 13th century. Then, in conjunction with the laboratories of EDF (Electricity of France) and the expertise of the Society Skertzo, elaborate lighting techniques were developed to project these colours directly on the façade with precision, recreating the polychromatic appearance of the 13th century. When projected on the statues around the portals, the result is a stunning display that brings the figures to life. The projected colors are faint to photograph, but a good quality DSLR will provide excellent results as shown here.
Of course, the full magical effect can best be appreciated by direct viewing, accompanied by stirring music, which can be done at the Son et lumière on Summer evenings, during the Christmas Fair, and over the New Year.
