In literature, the color "drab olive" is often employed to evoke a sense of faded brilliance or understated naturalness. For instance, one narrative describes a character whose once high and lively coloration has diminished, leaving him with a drab olive tone that hints at loss or decay ([1]). Similarly, the color is used to depict physical characteristics in a more detailed character portrayal, as seen in the description of a female figure whose drab olive complexion contrasts sharply with her bright yellow throat, suggesting both a natural subtlety and a flash of unexpected vibrancy ([2]).
