A brand identity prism is a strategic tool used to define your brand's core characteristics across six dimensions: Constitution: The company's values, personality, and culture. Relationship: How the brand interacts with its customers. Reflection: How the company perceives itself. Self-image: How the brand wants to be perceived by others. Culture: The brand's contribution to society. Developing a brand identity prism helps ensure all aspects of your brand – from messaging to marketing materials – are aligned and work together to create a cohesive brand experience.
