VS2010 color change

Every time I put a cursor on a variable in VS2010 it highlights it and any othe开发者_JAVA百科r place where its used with gray background. I know that in Fonts and Colors we can change color schemes. Which Display Item is responsible for this please ? Thank you,

The Display item is: "Highlighted Reference" (about 1/3 of the way down my list). :)

With the "Show settings for:" showing "Text Editor"

See below screenshot.

Hope this helps.
