White covers

I've been seeing a few white covers with low contrast around lately, like the ones below:

Given the current trend towards dark covers for young adult books, this could be a smart way for books like the ones above to stand out on the shelf. However, this kind of cover only works if the vast majority of the other books are not white, so as soon as it becomes a trend it loses a lot of its stand-out value.

The fact that the title of Julianna Baggott's Pure is not easy to read at a distance might actually work in its favour, if people are compelled to look more closely. This title is also notable for being published with two different covers: low-contrast white and low-contrast black.
