Installed dark theme in eclipse, but scrollbars is still grey

Question

I am using Eclipse Luna(4.4.0) and trying to make it completely dark. So I Installed a theme plugin:

Eclipse menu -> Help -> Eclipse Marketplace, search

Answer 1

1. cmd+space
2. System Preferences
3. General
4. Show scroll bars: "When scrolling" (see screenshot)

In my opinion though, this isn't a great solution because you don't see the scroll bar sometimes and sometimes it still shows the bright grey scroll bar depending on where you put your mouse.
