SOLVED. YA Rainbow themed Christian book series 2007-2014

[Dara]

I read this series in middle/high school. Each book was a different color, and the colors might have been incorporated in the titles. The books were all white with horizontal stripes of the book's color in different sizes spanning from the back to the front. The characters were always different, and the main character was struggling with a vice of some sort. I remember books about alcohol abuse, self harm, eating disorder, envy over losing a friend, and a girl becomes a wiccan in one of them. They seemed new-ish when I checked them out between 2007 and 2014, but could have been published prior to 2007. The main character was usually female. I don't think there were any illustrations on the front or back of the books.

Found it! I went to the library catalog in my hometown and tracked it down. The True Colors series!

Glad you found it! It sounded really familiar, and sure enough I’ve read part of Pitch Black. Never finished it though, and forgot about it till now!
