[sublimetext] Sublime Text 2: How do I change the color that the row number is highlighted?

On windows 7, find

C:\Users\Simion\AppData\Roaming\Sublime Text 2\Packages\Color Scheme - Default

Find your color scheme file, open it, and find lineHighlight.
Ex:

<key>lineHighlight</key>
<string>#ccc</string>

replace #ccc with your preferred background color.
