(Windows 7, Classic theme)
In Windows, a selected object is highlighted in dark blue. Selections in a window that does not have focus, are highlighted in gray. Here's an example from Windows Explorer. I've selected a PDF, and the current folder ('My documents') gets a gray highlight. So far, so good.
The folder named '005' is highlighted, but the highlight color is so light I can barely see it.
In an effort to increase visibility of this highlight, I've tried using one of the high visibility themes in Windows. That works: the colors of the remote desktop program change along with my local colors. But the high visibility themes look awful to me, so I'd rather not use those.
Is there a way to change just the color used for highlighting in background windows?
