I’m talking about the new Smart Invert Colors Accessibility option that has a similar effect. Compared to the classic Invert Colors feature, Smart Invert reverses the colors of the background, text and buttons but leaves images, icons and even entire apps that use dark colors unscathed. Considering that you can even assign a shortcut, it can be accepted as a handy workaround for an actual Dark Mode.
How To Enable Smart Invert Colors
1. Open the Settings app from your iPhone/iPad Home screen and tap on General.
2. Open the Accessibility menu.
3. In the Vision area, tap on Display Accommodations.
4. Next, select the Invert Colors menu.
5. Enable Smart Invert.
Tip: Tap Back, available in the top-left corner of the screen, twice to return to the Accessibility menu and configure the shortcut as explained below.
Assign Smart Invert Colors Shortcut
1. Within Settings -> General -> Accessibility scroll all the way down the screen.
2. Tap on Accessibility Shortcut.
3. Select Smart Invert Color and any other feature that you want to enable or disable via the triple-click home button gesture.
Facts: 1. The Smart Invert Colors option works optimally when used with native iOS apps like Phone, Messages, Photos, Settings but I’m not satisfied about how it displays in Safari.
2. Enabling Smart Invert Colors automatically disables Night Shift mode.
