The theme I was using stopped working after the new update so I made my own. I'm pretty sure I've found and remove most of, if not all, the remaining blue from tumblr. This style is also currently maintained as I am still using it myself. If anything does break, or I missed anything, please don't hesitate to let me know on my tumblr.

Pissed because there are some recommended posts on your dashboard? Who are those people? Why are the posts there? Where do I turn them off??... No worries, shit can be mended.
Removes the annoying ads from your dash. Let me know about any suggestions or if there's any issues. Enjoy! :)
