Vectorial versus functional statistical approaches to evaluate colour variations of tempera paints exposed to real environment

Abstract:
The colour changes of tempera paints exposed to the ambient depends on the composition of the paint (pigment, binder and the interaction between them) and the components of the atmosphere. In this paper several statistical techniques based on vector and functional approaches are presented in order to accurately stablish the trends of colour changes of paint mock ups composed of different pigments and binders and exposed to a real ambient. A functional approach of the statistical techniques applied are revealed much more useful than a vectorial (classic) approach in order to extract information about the colour variations during the exposure.
