Someone who loves the dark can be referred to as a "nyctophile." Nyctophiles are often drawn to the night and find comfort or pleasure in darkness, often appreciating the quiet and tranquility it brings. This attraction to the dark can be aesthetic or emotional, and it may influence their preferences in activities, environments, and even art.
