Hard to see highlighted occurrences of marked variable in dark theme #23

Thanks for the awesome theme, it immediately became my favourite one! 😍

However, I rely on VS Code highlighting all occurrences of a variable when my text cursor is placed in one. In the dark theme it is really hard to see those as the contrast between highlight and background is too low.

In following screenshot, the variable value occurs in lines 44, 67 and 72.
