Hello. I'm looking for a theme or skin that will turn the window background color of applications (including file explorer) to grey, cream, or some light color that's not very bright. Right now, I'm looking at the retro skin pack featured in the Winareo site, which was mentioned earlier. Also, I prefer using my current theme, which is just the default theme for Win 8.1 with my own wallpaper. I'd like to know what software can be used to make the color change so that I can do it myself.
