This conclusion is the result of a multidisciplinary study conducted by researchers from the Department of Prehistory, Archaeology, Ancient History, Medieval History, and Historiographical Sciences and Techniques at the University of Murcia, together with the Department of Organic Chemistry at the Chemical Institute for Energy and the Environment (IQUEMA) at the University of Córdoba. Through a range of analytical techniques, the remains discovered in the domus have revealed a unique combination of pigments never before documented in Hispania, with only one known parallel in Ephesus, Turkey.

As UCO researchers José Rafael Ruiz Arrebola and Daniel Cosano Hidalgo explain, they have published their research in the journal npj Heritage Science alongside archaeologists Gonzalo Castillo Alcántara, Alicia Fernández Díaz, and José Miguel Noguera Celdrán. The groups' multidisciplinary research is in line with previous work on topics such as the world's oldest wine and aromas that perfumed the Roman Empire. In this case, analyses carried out in the laboratories of the IQUEMA and FQM-346 research groups made it possible to determine the composition of the mortars used in the house through X-ray diffraction, as well as to identify pigment residues using Raman spectroscopy, a technique that detects chemical compounds based on how they interact with light.
