Egyptian blue has appeared in literature as a striking, evocative hue that delivers both a vivid sensory experience and a bridge to ancient splendor. In one narrative, it envelopes the sky with an almost magical intensity, setting a scene where the heavens themselves seem to wear this rare shade, as noted in [1]. Historical texts further describe its use in the grand architecture of antiquity—Vitruvius, for example, recognized Egyptian blue (or Cœruleum) as a celebrated pigment adorning the temple walls and even the cases of mummies [2]. Its luminous quality extends into depictions of art, where figures and objects are rendered in this distinctive color to evoke refined beauty and timeless allure [3], while potters are said to be irresistibly drawn to its captivating glow in their glazes [4].
