Primary Logo- The main visual of the brand that instantly conveys the brand's identity and values.
Secondary Logo- A flexible alternative to use when the primary logo is not appropriate or does not fit right. It's usually smaller and used for social media posts, and smaller spaces.
Submark Logo- This is a simplified version of the primary logo mostly into an icon or a graphic element representing the brand. It's used in tiny formats, for social media, online spaces, and compact spaces.
