The styling Oprah’s 111th book club pick features type in a shade of yellow that you’ll also see on the cover of the forthcoming “ Happiness & Love,” among others.

It turns out an old saying might be wrong. You can judge a book by its cover, in a sense. Authors and cover designers say there’s a lot you can glean from a book’s front.

Illustrated covers – bright colours, abstract figures, playful fonts – front the work of some of the genre’s biggest names, including Emily Henry, Sally Thorne, Jasmine Guillory and Helen Hoang.
