I once worked for an advertising agency at which every logo design and brochure had to pass an incredibly difficult test. At the end of the workday, one of the partners would put the piece in his briefcase, bring it home, and show it to his wife. As a result, we produced a lot of work that looked alike, usually using the same two or three colors (which I assume also dominated their home’s décor).
You might chuckle at the idea of a high-powered advertising executive basing his decision about what was best for client needs on Mrs. Executive’s personal likes and dislikes, but are you guilty of the same approach?
