title: Windows Phone 7.1 Light/Dark themes management
body: <p>How does exactly work themes switching in application? What if I override the default styles? Can I also define different styles for light and dark themes separately? Why the icons colos get changed - i.e. the black background of icons changes into white if the theme is set to Dark. Will it also be changed to white if I override the background style of application bar to white explicitly? How can I make sure nothing gets changed and my app looks the same in Light and Dark themes?</p>
