What is the name of this colour scheme element?

I have an annoying problem with Visual Studio highlighting. I installed my favourite colourscheme (zenburn 2010), and I have found that when I'm in debug mode, this will happen when my application is paused:

I have run through the hundred or so colours in the settings window, but I am unable to locate the setting that will affect this background colour. It's not exactly a show-stop开发者_JAVA技巧per, but I'd still really like to know how to solve this.

I have resharper installed in case that affects anything. I can't see how it would though.

I think you want either the Collapsible Region element, or the Selected Text element

Changing the background color of the Read-Only Region element solved the issue for me. (See this article for more detail.)
