I used Devine Color paint in Devine Horizon sold at Target. However, it was a little too blue for my liking so I added green paint to it until I got to the color that I liked.
The after bookshelf: not boring, freshly dusted, fun, mint/black. I didn't want to paint the entire thing mint because I felt it would be a bit much. So I painted the back of it and the front of the shelves. I think it came out super cute! And it was incredibly easy and only took about an hour.
