Sometimes, you change your app's UI to offer more options as a result of a user's action. And in such cases, it might be a good idea to move VoiceOver's focus to these new options. We can do that by sending a layout changed notification.
You should convey important information in multiple modes, not just color. If you are still required to do so, at the very least you should complement that info with other modes, like symbols, if the user requested differentiation without color.
