Expression refers to the process of conveying thoughts, emotions, or ideas through various forms of communication, including art, music, and language. It allows individuals to share their inner experiences and connect with others on a deeper level. Artists often use their work as a medium for self-expression, reflecting their personal narratives and societal issues. In the realm of visual arts, expression can manifest through techniques, colors, and styles that evoke specific feelings or reactions. For instance, Vincent van Gogh's use of vibrant colors and dynamic brushstrokes in paintings like Starry Night exemplifies emotional expression, inviting viewers to experience his perspective of the world.
