Swapped to this script after rubyruby's script broke and they said they wouldn't continue it. This mostly works but there's a few issues
Dashboard's background is the old blue, but there's a bit of new blue with a gradient under "Explore all of Tumblr"
The icons and buttons are using the new neon blue instead of the old colours, eg. the number on the dashboard icon, the new post button, and the "Explore all of Tumblr" text are all neon blue
If you have somebody's blog up on the side, the background returns to the new blue
Partially working, not fully

Hope this helped!
