From the Chapel of Nª Sª de los Dolores:
The predella of the altarpiece of the Virgen de los Dolores was painted with a thick layer of brown paint applied at the time to integrate the whole with the wooden step that rests on the altar. When the restoration work began, it was possible to verify that this repainting was on the original polychromy that shows the rest of the niche. Therefore, the decision was made to remove the overpainting to recover the ocher marbling that the predella originally had. Using a combination of solvent gels and in some cases removing the brown paint at the point of a scalpel, the desired result has been achieved. What we can see in the following images:
