In literature, the use of cyan often straddles both aesthetic description and technical precision. One author characterizes a “pure blue tending toward cyan blue” as a luminous shade enriched by hints of green, thus emphasizing its unique vibrancy ([1]). Meanwhile, in more functional contexts such as printing theory, cyan emerges as one of the essential colors—paired with yellow, magenta, and black—to achieve the full spectrum of images ([2], [3]). This dual display of cyan—as an evocative hue in artistic description and as a key component in technological processes—illustrates its enduring role in conveying both beauty and utility.
