Apple takes very seriously the accessibility of all devices and therefore with each new version of iOS or OS X often include new options for anyone to use. One of the latest additions to this section is grayscale mode and then explain how you can turn this mode on iPhone, iPad and iPod Touch.
This grayscale mode is primarily intended to be used as an option to improve accessibility for people with certain vision problems, but can also give other uses if desired.
Mode grayscale or black and white in iOS
Mode grayscale in iOS is really simple. We just follow these steps:
We played on the app settings and access to the General option - Accessibility.
In the Vision section we activate the Grayscale option.
Grayscale enabled on iPhone and iPad
That's all, at the time of placing the switch in the ON position, the mode is enabled and the saturation of colors will be removed, passing display the entire contents of the screen in a gray scale, primarily in black and white.
As mentioned, this mode is thinking especially for people with impaired vision and colorblind. Thanks to him, the screen elements become easier to interpret for people with such problems. In addition, this mode can also be used in other circumstances, for example, as an alternative method of viewing in dark or low light areas, to facilitate navigation through websites where colors can be too garish or simply for a touch different from our iPhone and iPad, and spend some time at a "different" operating system.
Grayscale mode IOS
Grayscale mode affects only IOS what is shown on screen, but really all still available in color. This means that, although showing in black and white, if we make a photo is saved with all the color information and the same goes for movies or other media content.
In addition, it can be a very good choice to spend a harmless prank on a friend who does not know very well the accessibility features of your iPhone or iPad. Sure it goes crazy trying to return the device to its original state :).
