The book titled '뷰티-풀' (Beautifu-l) is a visually striking Korean creative work that features an abstract, watercolor-style illustration. The cover art deftly conveys a sense of mystery and introspection, showcasing a building and landscape set against a dark, atmospheric sky. The dominant colors are muted greys and blacks, enhanced by a touch of white that highlights the building's structure, creating a contrast that draws the eye. The fluidity of the watercolor strokes and the absence of sharp lines contribute to the overall dreamlike quality of the artwork. This artistic choice evokes feelings of serenity but also a hint of unease, encouraging deeper contemplation of the themes presented within the book.
