Thanks for contacting us.
Would you tell me what tool you are using in order to set dark theme in VS 10?
Some screenshots or video of the problem would be helpful too.
Meanwhile, you can try to set a different color for "JustCode Outline Marker" located at VS "Fonts and Colors" settings.
I look forward to hearing from you.
