Chrome Recognizing Themes

I am confused with using themes and viewing them with Chrome.
When I change the Maine theme, Chrome does not change but if I change the Widget theme than Chrome changes.
From what I can tell is that Chrome uses the widget theme.
No matter what I do it seems that Chrome with now recognize the Main theme.
Explorer seems to use the Main theme but Chrome seems to use the widget theme.
Is this true or is there a way to make Chrome use the Main theme?
