Lumiere Technology, a start-up based in Paris, reveals the true colors of the Mona Lisa. Pascal Cotte, engineer and founder of Lumiere Technology, largely contributed to the knowledge of the Mona Lisa thanks to the multispectral digitization of the famous painting, whose report is detailed in the famous book "Mona Lisa - Inside the Painting", recently published by Abrams in USA, Gallimard & the Editions of the Louvre in France, Shirmer Mosel in Germany. The hidden knowledge of the true colors was revealed by multispectrally scanning the painting in thirteen channels - from Ultra Violet to Infra Red. Then the spectral response curve of the varnish in each pixel was isolated and subtracted from the digital file to virtually reveal the surface of the painting when it had freshly exited Leonardo da Vinci's workshop. This virtual removal of years of accumulated varnish is an illustration of Lumiere Technology's technical knowledge that will now be marketed as an exclusive digitization service to museums and private fine art collections worldwide. The true revolution that Pascal Cotte developed enables the in-depth study of fine art paintings using a numerical file to reveal the true pigments for viewing and analysis without touching or damaging the paintings. Lumiere Technology offers this service to museums worldwide as a unique, single tool to assess, analyze, authenticate, restore and reproduce their masterpieces of fine art.
