    As rendering engines become increasingly important in film and television, with their use in virtual production (VP), some underlying issues become more apparent. This paper aims to investigate how we can improve asset color matching of VP elements with real-life objects found on sets. Experiments were conducted in which objects were exposed to various types of lighting setups, and digital twins were rendered using both RGB methods and spectral methods, with data reduction techniques also employed. The renderings were then filmed, alongside their real-life counterparts. Color difference metrics were used to determine whether spectral rendering and data reduction techniques offered advantages over RGB renderings. The conclusion illustrates that spectral rendering offers advantages, including higher accuracy in rendering the colours of materials.
