The blue color on the Ottoman ceramic artifacts can be studied from the perspectives of different sciences: in terms of color aesthetics, which is a kind of philosophy of beauty, or as part of the science of photography and graphics. Additionally, for some communities the importance of this color lies at the heart of anthropology, but it is also at the core Islamic art and archeology. Blue is one of the original colors that humans have known since ancient times. It is associated with the elements of nature as it symbolizes the sky, sea, and serenity. This color is especially important in popular beliefs as we find a lot of amulets that use the blue color especially those which are believed to avert the eyes of envy. The blue color has appeared on many of the Ottoman Islamic artifacts, especially ceramic artifacts, since ceramics were among the most used materials in life which expressed the social and intellectual life of both artists and manufacturers. The research will analyze the importance of the blue color of ceramic artifacts in the study of heritage and archaeology and how these blue decorative elements on these ceramic pieces relate to social life.
