The color scheme of a logo plays a crucial role in brand recognition and appeal. A good-looking logo color should be visually appealing, easily distinguishable, and culturally relevant. It should also complement the logo's design and convey the brand's message or values. The choice of colors should be based on color theory, which includes aspects like color harmony, contrast, and symbolism. Companies often use color psychology to select colors that evoke certain emotions or convey a specific brand personality.
