Smart Invert in iOS 11 is as close to Dark Mode as Apple gets for now
Perhaps it has something to do with joining the dark side, but Apple has teased us for years about a system-wide Dark Mode and has never delivered. Perhaps the force is not strong enough to make this a feature on iOS even though every year there is a rumor that it is coming. While iOS does have an Invert Color feature, this is not exactly what the Apple faithful have been hoping for. The latter feature will invert colors used on photos, emoji and Message attachments.
But with iOS 11 comes Smart Invert. This brings users the same features as Invert Color, but is smarter. In other words, it will work throughout an iPhone's system, but will not touch photographs. It also will not turn apps from black to white. For example, the clock app will remain black.
Those using a beta version of iOS 11 on their iPhone can check out Smart Invert by following these directions. Go to Settings > General > Accessibility > Display Accommodations > Invert Colors > Smart Invert. And since a public beta version of iOS 11 has been released, you don't have to be a developer to check it out.
Clicking on the video at the top of the story will show you how to activate Smart Invert. Also, while viewing the video, note that the older version of the Invert feature is now called Classic Invert.
