Evidence
"Therefore, we have concluded that the SERS spectrum of the pink crimson pigment, used in the studied Moroccan artworks, corresponds to the cochineal carmine extract."
Remarks
Found on manuscripts MEK-MS-1 and MEK-MS-4 (p. 117). Carmine is noted to be ten times more colorant than kermes. Cochineal was imported from Mexico to Europe in the late 16th century, while kermes is native to southern Europe (p. 117).
