For example, if you need to shade\u00a0the iPhone&#8217;s entire display permanently reddish in order to preserve night-time dark adaption, you can do that. This technique would be particularly handy for amateur astronomers. While some astronomy apps have this feature, this tip applies to the iPhone&#8217;s display across the board. The tip is beautifully described, including an explanation of accessibility shortcuts, and also invites exploration\u00a0for those who have certain kinds of color blindness.
