SHADES of conservation: prediction of colour fading in artworks

Objetivo

Colour in art is more than mere decoration; it is a vital element of human expression and cultural heritage. Polychrome artworks offer profound insights into historical practices, societal values, and technological advancements across different cultures. Yet, these colours are highly susceptible to deterioration, particularly when exposed to light. Photo-degradation is a complex process and remains unpredictable today, causing irreversible changes that result in fading and alteration of hues. This not only compromises the aesthetic and material integrity of the artefacts but also impedes our ability to fully comprehend the artist’s original vision and poses significant challenges for preserving these invaluable treasures. SHADES introduces an innovative method for detecting and predicting colour fading before it becomes visible to the naked eye. This approach utilises Fluorescence Lifetime Imaging Microscopy (FLIM) to capture lifetime signal shifts, allowing us to address the inherent unpredictability of photo-degradation. By analysing mock-ups created with traditional recipes for common polychrome layers (binder, dye, and varnish) and subjecting them to controlled exposure to mono- and polychromatic light, we aim to: i) identify the unique 'fingerprint' of each material; ii) monitor signal shifts indicative of photo-degradation; and iii) develop a predictive model to detect colour changes before they are perceptible. By integrating various disciplines, SHADES is set to revolutionise the field of material degradation and conservation. The project will yield accurate predictive models and advanced techniques for preserving polychrome artworks, addressing colour fading before it becomes visible. Its impact extends beyond conservation and restoration, influencing museum exhibitions where light management is critical and advancing material science, ensuring the enduring vibrancy and historical integrity of these priceless artworks.
