[automatically translated] The realization of spectrophotometric investigations for the monitoring of color changes is the need to manage a large number of data by requiring the use of statistical analysis. For this purpose, the PCA was applied to spectrophotometric data relating to different types of surfaces (mosaic, marble, etc.). This methodology allows to effectively assess the effects generated as a result of the restau; ro, highlighting the correlation between all spectrophotometric variables. The data distribution in the cluster displays the variable that contributes most to the color shift, allowing the differentiated monitoring of the behavior of surfaces having different color, subjected to the same treatment.
