Make interface colors more consistent

Current behavior

Improved behavior

There is a weird split between the left being lighter and the right being darker. Additionally the editor is a different color gray, and while the eyes should be drawn to the editor, as it is the most important component of the app.

I'm going to deal with it.

The major problem is the current app is using colors with transparency. I think it is quite hard to control so I'm going to make it more solid without any transparency.

I am closing this as it is outdated, new local space has few themes which are very nice looking.
