A mood board is a visual tool used to convey ideas and concepts through images, colors, textures, and typography. It serves as a collage that captures the desired mood or style for a project, making it easier to communicate creative visions. Mood boards are commonly used in fields like interior design, fashion, and graphic design. Creating a mood board can help streamline the design process by providing a reference point for inspiration and direction. It allows designers and clients to align their expectations and ensures that everyone involved shares a common understanding of the project's aesthetic goals.
