Variable Names in Debugger Console Almost Invisible (Color Theme Darcula)

I've been trying to find the entry point for changing the color for Variables in the debugger console window (picture below), but I can't seem to find it. As you can see on the picture below, the variable names are difficult to discern due to the dark blue color against the dark background.

This otherwise very pleasant color scheme is wearing me out since I have to select a line in the panel (which makes the text white) in order to be able to read the variable names.

Perhaps someone here can point me to the entry point for modifying this color?
