For clarity, what exactly *is* the workaround here? OP is on Windows 7 (as am I). @elextr seems to indicate that futzing with the GTK theme is not effective for Windows.
And granted, there is no obvious and direct correspondence between programming syntax elements and GUI elements, but at a minimum there could at least be an "overall dark UI" setting, even if it is not specifically matched to the syntax coloring.
Question for @AnthonyVO - did you ever find an acceptable workaround?
