Gadi Sagiv's book Jewish Blues: A History of a Color in Judaism (U Pennsylvania Press, 2023) presents a broad cultural, social, and intellectual history of the color blue in Jewish life between the sixteenth and twenty-first centuries. Bridging diverse domains such as religious law, mysticism, eschatology, as well as clothing and literature, this book contends that, by way of a protracted process, the color blue has constituted a means through which Jews have understood themselves.

In ancient Jewish texts, the term for blue, tekhelet, denotes a dye that serves Jewish ritual purposes. In addition, blue features prominently in the Jewish mystical tradition, in Jewish magic and popular custom, and in Jewish eschatology. Blue is also representative of the Zionist movement, and it is the only chromatic color in the national flag of the State of Israel.

Through the study of the changing roles and meanings attributed to the color blue in Judaism, Jewish Blues sheds new light on the power of a visual symbol in shaping the imagination of Jews throughout history. The use of the color blue continues to reflect pressing issues for Jews in our present era, as it has become a symbol of Jewish modernity.
