问题
I would like to change the title bar's background colour. I see in the xml file which produces the title. What is the way to hook into the title bar to change the background colour? I see a similar questions for C# [Is there any way to change border/header background in VSTO outlook add in?][1]
[1]: Is there any way to change border/header background in VSTO outlook add in? Is there something similar we can do here with the webaddin?

Currently changing the background color of the title bar is not a part of the product. We track Outlook add-in feature requests on our user-voice page. Please add your request there. Feature requests on user-voice are considered, when we go through our planning process
