I’m going to mark this as completed so you can get your votes back – note that Matthew Johnson has released a VS 2012 color theme editor as you requested (link below) – I know it doesn’t have everything you requested in this idea, but hopefully this helps to address your feedback.
Doug Turnure – Visual Studio PMVS commented
I have installed the Color Theme Editor and tested some themes.
But with none of the themes I can see, whether the Visual Studio or any other window has the focus.
Which settings changes the color of the top line (with "Projectname - Microsoft Visual Studio (Administrator)") depending on the focus of the Visual Studio?
