Brand guidelines outline the rules for how a brand presents itself visually and verbally. They include details like the brand's history and values, approved logo usage and sizing, approved color palettes, approved typefaces, photography styles, and templates for business cards and letterheads. Maintaining a consistent brand identity through visual elements like colors, fonts, and graphics helps customers easily recognize the brand. While the brand identity is constructed by the company, the brand image is how customers actually perceive the brand. Color is an important part of any brand identity since colors can impact emotions and focus. Testing how audiences respond to a brand's colors is advised.
