**Appendix B**

The main findings from spectroscopic techniques are presented in the following tables, grouped by colors. Acquisition region is indicated, as well as ID for XRF and FORS acquisition points. In some cases, both spectroscopic techniques correspond with the same geometric spot, although they have different ID numbers. Elements reported are sorted in descending order by the intensity of their most intense characteristic X-ray line. Each pigment's representative elements are highlighted.



## **Table A2.** Blue.


## **Table A3.** Red.


## **Table A4.** Brown.


## **Table A5.** Green.
