Apple designers and developers are constantly working to offer new features and enhance the experience of using bitten apple products.

For example take iOS: the operating system of iPhone and iPad is continually subject to minor updates, which improve security and allow users to take advantage of new features.

But with the major update presented during the various WWDC and released annually, that Apple releases the biggest news for its operating systems iOS in the lead.

The 2017 release was particularly important for the Cupertino house: iOS 11, in fact, was released concurrently with the release of the iPhone X, the iPhone created to celebrate the tenth anniversary of the “series”.

special version of the operating system for mobile devices, designed to redefine the experience of using iPhones and iPads. Among the many novelties iOS 11 stand out, for example, the new Control Center, the augmented reality support with ARKit and No Driving Disorder.

Another feature introduced with iOS 11, despite greatly improving the user experience of the iPhone, often goes unnoticed. After introducing Night Shift with iOS 9.3,

Apple introduces a new display mode designed to reduce visual fatigue while using the iPhone. This is the so-called “Invert colors” or dark mode and is one of the biggest news iOS 11.

What is the purpose of the “Invert colors” feature?

Like the Night Shift, even the Invert Colors can be considered a way to reduce eye strain when using the smartphone at night or in the dark.

The light emitted from the display LEDs (or from the OLED panel, depending on the model used) can create a very strong contrast with the surrounding environment and cause severe tearing or tired eyesight.

The dark mode, at the same time, can be considered a high contrast mode and therefore a great help for users with problems of various nature to the eye.

Activating the Invert colors, therefore, it will be easier to use the iPhone or the iPad even for those with a visual handicap.

The inverted colors, finally, is also a trick to save iPhone X battery. The OLED screens, in fact, do not consume energy to produce (and reproduce) black pixels: with the dark mode, most of the screen will be black and will not reduce battery life.

In short, if you are not at home or in the office and the iPhone X is about to unload, activating the Invert colors you can earn a few tens of minutes more than using the device and be able to go home (or return to the office) without too much trouble.

Night Shift and Invert colors are the same things?

Although in part, their features overlap, Night Shift and Invert Colors are two very different features. Night Shift, available not only on iPhone and iPad but also on iMac and Macbook, change the screen tone, adding a blue filter that eliminates the bluish component of the light and allows you to rest your eyes and avoid disturbances during the rest.

Invert colors, as seen, completely change the user interface, substituting the dark shades with darker shades such as black and grayscale.

How to activate Invert colors on iPhone and iPad

To activate the dark mode on iPhone compatible with iOS 11 will only take a few seconds: just know where to find the “switch” and you’re done. Open the Setting of the iPhone, press on Accessibility and then on Screen Adjustments.

In this menu, click on Invert colors: at this point activate Smart color inversion or Classic color inversion according to your needs. To deactivate the dark mode, simply enter the Invert Colors menu again and deactivate the chosen option.

Differences between Smart Color Inversion and Classic Color Inversion

Apple’s choice to include two dark mode modes in iOS 11 is not at all random. While Classic Color Inversion changes all the colors of the GUI, with Smart Color Inversion changing colors will be the background and other “minor” graphics, while the style of images, multimedia files and apps that already use dark backgrounds will remain the same colour.
