tool offers a risk assessment method to help prevent unwanted colour changes. By combining the spectral profile of your chosen light source with known data on the colour change or fading behaviour of pigments and materials, the LDE lets you explore how different lighting conditions could affect specific areas of an artwork.<\/p>\n<p class=\"custom-font\">You can use it to customise lighting setups for each object, define safe exposure limits and strike the right balance between preservation and presentation. Want to experiment? The tool also lets you simulate and visualise the results of different scenarios, helping you to make informed decisions about protecting cultural heritage while still displaying it in optimal light conditions.<\/p>\n<h6>Credits<\/h6>\n<p class=\"custom-font\">\n<ul>\n<li>Primary Credits: Panagiotis Siozos <a href=\"https:\/\/orcid.org\/0000-0002-4836-5557\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (FORTH), Irina-Mihaela Ciortan <a href=\"https:\/\/orcid.org\/0000-0003-0541-1039\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (NTNU), Petros Stavroulakis <a href=\"https:\/\/orcid.org\/0000-0001-9914-7261\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (FORTH), Gautier Rollin (IMKI), Sophia Sotiropoulou <a href=\"https:\/\/orcid.org\/0000-0001-9146-8474\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (FORTH)<\/li>\n<li>Secondary Credits: Giorgio Trumpy <a href=\"https:\/\/orcid.org\/0000-0001-9534-0507\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (NTNU), Letizia Monico <a href=\"https:\/\/orcid.org\/0000-0001-9489-7805\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (CNR SCITEC), David Buti <a href=\"https:\/\/orcid.org\/0000-0001-6347-6506\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (CNR ISPC), Brenda Doherty <a href=\"https:\/\/orcid.org\/0000-0002-9326-2143\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (CNR SCITEC), Catarina Monteiro Pinto <a href=\"https:\/\/orcid.org\/0000-0001-9413-3215\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/perceive-horizon.eu\/wp-content\/uploads\/2025\/08\/orcid.png\" alt=\"ORCID\" width=\"18\" height=\"18\"><\/a> (CNR SCITEC), Irina C.
