The iPhone has a built-in ability to turn off all colors on the screen, leaving only grayscale with 2 black-white display colors, but few people know about it. The purpose of this mode is to help people with color blindness read text more easily, avoiding distractions from other display content.
iPhone switches to black and white mode to help... reduce excitement when using the phone.
Should people who are not color blind switch their iPhone screen to black and white?
Even if you’re not color blind, there are reasons to switch your iPhone to black and white mode. Monochrome screens have been shown to be effective in reducing distractions while using the device, and they also reduce screen time because the device is no longer vibrant, making it less enjoyable to use. Black and white mode makes social media sites like Instagram look washed out, websites look dull, and games look much more monotonous.
This decision may be difficult at first due to changing usage habits and making the phone more boring, but it has the positive effect of creating motivation for users to be less "glued" to this device.
Another reason to consider is the ability to avoid distraction. App developers understand that color plays an important role in attracting users’ attention – a big reason why they always create bright red notifications in their apps to draw users’ eyes to them, compelling them to tap to see what’s new. If a screen is all black and white, this purpose is lost, and users are more likely to focus on other tasks.
Another benefit that cannot be ignored is that the black and white screen helps reduce eye fatigue during continuous, long-term use. Monochrome screens reduce contrast and stimulate the eyes, helping to avoid eye fatigue and headaches, especially for those who have to look at the screen a lot.
How to enable black and white mode on iPhone
To turn the screen to black and white display on iPhone, users follow the instructions below:
On your phone, go to Settings -> Accessibility
Select Display & Text Size
Click Color Filters
Slide the switch to On (green light)
Select Grayscale. Now your iPhone screen will display completely in black and white.
Below the interface, there will be an additional Intensity section, which is shown as a left/right slider (indicating the increase or decrease). At maximum level (all the way to the right), the screen is completely black/white and gradually decreases in intensity (meaning the appearance of other colors) when dragging the button to the left.
This mode can be turned off by going to Settings -> Accessibility -> Display & Text Size -> Color Filters -> slide the switch to Off (gray). The screen will now return to its original multi-color state .
