In literature, "mellow gold" often emerges as a warm, evocative hue that transforms ordinary scenes into realms of soft illumination and nostalgic beauty. For instance, authors describe mornings and sunsets bathed in a gentle, golden light—turning a simple sunrise into an atmosphere rife with tender promise, as seen in [1] and [2]. The color is equally effective in conveying the lush ambiance of autumn, where diffused rays drape interiors and landscapes alike in a comforting glow ([3], [4]), and even architecture is imbued with a serene opulence, such as the "mellow golden roof" in [5]. Beyond daylight, "mellow gold" can carry an ethereal quality when it spills over settings of enchanting music or moonlit enchantments ([6], [7], [8]), demonstrating its versatile role in evoking both the natural and the supernatural.
