Visual Studio 2010 + ReSharper 5.1 Class Highlighting Problem

I have recently started using Visual Studio 2010 and ReSharper 5.1. It's working pretty well for me so far except for this one issue which I'm hoping someone has the answer for. Basically, like many others, I tend to use a dark colour scheme to improve readability over the default VS colour scheme. Having installed ReSharper I have noticed that when I navigate 开发者_开发知识库to a class name, the class name and any references to it get highlighted. That in itself is fine but with the colour scheme I've chosen, I'm getting a light-on-light combination which is unreadable.

I've gone through the Tools->Options->Fonts and Colors menu a few times but there doesn't seem to be an appropriate ReSharper item.

Here is a screenshot illustrating the highlighting problem

Set Highlighted Reference background color. It is not resharper one.
