Change window frame color on an application basis

Question

Although I can change the global theme of Windows, all the elements of the OS have the same color scheme. I would like the scrollbars, buttons, etc on win 8.1, to be different for different applications. In other words, something like themes applied to each application.

Answer 1

Stardock WindowBlinds can do this. I personally own a copy of this program, so I can say it works. From the link:

Per application skinning

Choose skins for each of your application types. For example, WindowBlinds enables your word processing software to use a different skin than your design programs.

Keep in mind, however, that any application which does not use the standard Windows widgets can, at its option, ignore any theme settings that you try to apply. It doesn't even have to respect your window borders; an application can render its own if it wants to.

WindowBlinds will work for many applications that use native Windows widgets and/or window borders, such as Qt, SWT, ATL, .NET WinForms and WPF. There are other toolkits for drawing GUIs, however, where only the window border effects will be applied; for example, Swing, GTK, wxWidgets, Motif, etc. And then certain applications, like Firefox and Chrome, can either optionally, or by design (with no option to change it), tell Windows not to draw any borders around its windows, which means that, if it then uses non-standard widgets, your customizations would be entirely absent.

It's not perfect, and there's no universal solution, but this should take care of "most" applications.
