Is there a way to change the "highlighted file" color on Windows 7?

"Edit:

If you mean the hot-track effect it's probbly not possible to ""manually"" tweak it.

I just found this to clarify it:

In regard to Windows 7, I came across
this interesting piece of information:
When hovering over the icons in the
taskbar, the color highlight of the
“glass” button is actually different
from application to application. How
it works is dynamically abstracting
the color values of the application
icon to find the most dominant RGB
value. Besides the obvious eye-candy,
this feature delivers some sentimental
value by making it easy to identify
applications by color.

The only thing you can do is try to change your Theme settings.

Its under Personalization, Window Color and Appearance, Advanced Appearance options under ""Selected items""

Two options you should try:

Standard Windows color settings:

Or the Aero theme colors:"

"If I remember correctly, going on my experience of modifying XP themes many years ago, it is not a colour value, but a bitmap graphic that you will need to change.

You will need to use Resource Hacker (last beta version for x64) or similar resource like XN Resource Editor and open shellstyle.dll.

The light blue bitmap will be in there somewhere. I'm sure someone on deviantart.com will know precisely where."
