Remarks

In the context of Najdi manuscript manufacture, colored inks served as the primary pigments for titles and decorative elements (p. 7). The study specifically identifies four primary colors (red, yellow, green, and blue) used by local scribes and illustrators (p. 11-12). These materials are discussed within the framework of artistic characteristics ('khasa'is fanniya') of the region's manuscripts (p. 18).
