Ingredient brands have a right to enforce their program identity standards on the companies that use their ingredients. A well-executed program finds a way for ingredient logos to add to the program identity. Often, the ingredient brands lend credibility, like medals on a scout uniform.
Whether the lead brand is Mac-compatible or as-seen-on-Food Network, the visual vocabulary established by a standardized program treatment clearly implies the business relationship.
The Bookmarked Club builds on the recognizable Target brand, while the Bags identity program stands on its own in contrast with the graphic identity of whatever the airline the company may be servicing.
