matchy-matchy
adj.— «If you’ve been following this blog, you know that I harbor a particular brand of irritation for matchy matchy book covers. Particularly matchy book covers that seem designed to identify these books to readers as books that go together, should be purchased together, are related to one another and in general, seem to scream “this is more about marketing than the quality of the writing.”» —“When A Cover Is Just That (and when might it be more?)” by Callie Miller Counterbalance (Los Angeles, California) Sept. 6, 2006.
