I'm on Windows 7. I have a problem with my desktop background - I use the Community Showcase: Natural Landscapes 2 theme. Very nice it is too.
Windows 7 allows transparency on window borders (as well as the Start Menu and Taskbar). I like this feature, so I've enabled it. However, when I'm using (for example) Excel on my second monitor, the black bars combined with the windows border transparency makes it tricky to read the filename (especially given I use a privacy screen).
What I'd like to do is change my desktop background colour from black to something a bit lighter so there's more contrast between filename text and background.
What I've tried
I could turn transparency off, but that would also turn it off on the taskbar and start menu. I like the transparency, so would like to avoid this. Neither changing the colour tone of the transparent effect, or increasing the intensity of the transparency colour makes a difference.
I've tried searching for tips on how to change the desktop settings in Windows 7 but they all want to tell me how to change the background image, not the actual desktop canvas colour.
In the days of Windows XP and earlier, I'd go into Display Properties and just set the background colour. In Windows 7 this option seems to have gone.
