I pulled my copy off the shelf to check. The most common paperback edition has this really stark, almost clinical white background. The title 'Verity' is in a bold, serif font colored a deep crimson red—it looks like dried blood, which is absolutely the point. Then there's this single, delicate black stem with a couple of thorns winding up from the bottom. The author's name, Colleen Hoover, is in a softer gray. So it's predominantly white, red, black, and gray. The contrast is brutal and effective; it feels clean but violent, which mirrors the book's content perfectly. It's a cover that makes you pause before you even open it.
I've seen some special editions with slightly different tones, like a cream instead of pure white, but that core combination of blood red, stark white, and sharp black seems intentional. It avoids any warmth, which fits a story about uncovering a writer's dark manuscript.
