iPhone provides the black-and-white mode for colorblind people to operate the phone just as ordinary people do. However, it is a reversible setting; whenever you want colors back, you get them by turning off the setting. But, sometimes, iPhone colors disappear automatically, which is confusing and frustrating, especially for those unaware of this feature.
Is your iPhone turned black and white? There could be multiple reasons behind this issue, such as custom settings, hardware, and jailbreak. However, whatever the issue is, you don't need to worry anymore. This article will provide accessible settings and solutions to eliminate your iPhone's black-and-white mode.
In this article
3 Possible Reasons for iPhone Black and White
Following are the three possible reasons for iPhone Black and white.
1. Grayscale
Your phone turns black and white because of the Grayscale feature, which can turn on accidentally. Grayscale is an accessibility setting first introduced in iOS 8. The primary purpose of grayscale mode is to make it easier for colorblind eyes to read and view things better. But when it accidentally turns on, it can be frustrating for people who don't need this feature.

2. Hardware problems
Even though the new iPhone 12 is a beautiful update to the old iPhone design, the user faces the annoying iPhone 12 OLED screen issue, in which the device's screen acts strangely. Some people might see a bright color, while others might see dark spots on the screen. Overall, the problem is very annoying, especially considering that these phones are supposed to be more significant.
3. Failed Jailbreak
If you've jailbroken your iPhone, it might turn black and white from time to time. Because when an iPhone has been "jailbroken", users can skip the steps Apple uses to ensure users only download apps that don't have viruses. This makes it much more likely that a virus or other lousy software will get on the phone. So, a virus attack can sometimes turn a jailbroken iPhone black and white.
3 Easy Fixes for iPhone Black and White

You can force your iPhone to restart to bring its colors back. But each iPhone model has a different way to force restart it.

iPhone 6/6S:
