In literature, fog is often evoked not only as a weather condition but as a distinctive, almost painterly color that imbues scenes with a surreal, otherworldly quality. For instance, Oscar Wilde’s verse [1] describes a “yellow fog” that creeps over cityscapes, effectively transforming ordinary urban landscapes into environments tinged with an eerie, uncanny glow. Similarly, other works evoke a “gray fog” that seems to hang heavily over everything [2], suggesting moodiness, melancholy, or uncertainty. In these uses, fog transcends its literal existence to become a vivid chromatic metaphor—its shifting hues reflecting the transient emotions and blurred realities in the narrative.
