In literature, "chestnut" is often used as a rich, warm color that evokes natural beauty and depth. Authors frequently employ the term to describe hair, lending their characters an earthy elegance; for instance, phrases like "chestnut hair" and "bright chestnut locks" ([1], [2], [3], [4], [5]) emphasize both vibrancy and subtle warmth. Similarly, the color appears in descriptions of animal features and other natural elements, as seen in depictions of a "chestnut-maroon" shade or "dark chestnut spots" that contribute to a realistic and tactile portrayal of texture ([6], [7], [8], [9]). These uses underscore how the color chestnut functions not just as a visual detail, but as a literary device that enriches characterization and settings with a familiar, comforting glow.
