A logo fundamentally consists of colors and shapes as well as words and ideas.
Logos typically use visual elements such as colors and shapes to create a recognizable brand identity, and they may also include text or concepts that convey the brand's message, values, or mission. While sounds and music can complement a brand's identity in other contexts, they are not essential components of a logo itself. Therefore, the most accurate understanding of a logo would encompass both visual elements and the conceptual ideas they represent.
