greyscale

In this article, I’m going to show you what to do when your iPhone is Black and White. The best part about this is that it’s very easy to fix and you’re definitely going to get your iPhone back to its normal white screen. I’ll show you why your iPhone turned black and white and how you can fix it.

You have probably been messing around with the settings app for your iPhone to turn Black and white because it shouldn’t happen by itself. If you have an iPhone, iPad, or iPad, beware of this settings and make sure that it doesn’t happen again.

The Reason your iPhone is Black and White

As I mentioned before, your iPhone has turned Black and White is because of the grayscale feature in the Settings app. This feature was introduced in iOS 8 and it allows you to make your screen black and white. Many iPhone users have accidentally turned Grayscale on and they don’t even realise it.

Here’s the meaning of Greyscale, ‘a grayscale or greyscale image is one in which the value of each pixel is a single sample representing only an amount of light, that is, it carries only intensity information. Images of this sort, also known as black-and-white or monochrome, are composed exclusively of shades of grey, varying from black at the weakest intensity to white at the strongest’.

How to Turn of Grayscale

The reason your iPhone screen has turned black and white is because of the Greyscale feature. If you have an iPhone, iPad or iPad, Grayscale can be found in many places in the settings app but the easiest way to turn it off is to go to the Settings app > go to General > Accessibility > Display accommodation > toggle off colour filters.

Colour Filters

The accessibility to these settings was changed in iOS 11 and this is the newest way to turn off greyscale. If you’re on an older version, you can turn off Greyscale by staying in accessibility and toggling off Greyscale.

When you’re in the colour filters section, you’ll see that your iPhone is on Greyscale and you’ll also notice that there’s a bunch of other colours there as well.

If you do have the colour filters switched on, you’re going to see, Red/Green Filter, Green/Red Filter, Blue/Yellow Filter, and Colour Tint. You want to stay away from Greyscale and Colour Tint the most because these are the filters that are going to affect your iPhone screen the most.

Another Place to Turn Greyscale off

If you’ve tried the steps above and you’re wondering why your iPhone’s screen is still black and white or you’re wondering why Greyscale wasn’t even on when you looked there, it’s because there is another section in the settings app that allows you to turn off Greyscale.

This new place to access Greyscale isn’t brought to the attention of others and not many people know about it. There are two places Greyscale can be accessed from in the Accessibility settings and if it’s turned on in one place and not in another place, it’s going to remain on.

To turn of Greyscale:

  • Go to the Settings app
  • Scroll down to General
  • Tap on Accessibility
  • Tap on Zoom
  • Then, zoom filter
  • Tap on ‘None’

This feature is so hidden so don’t blame yourself and feel stupid because the normal iPhone users wouldn’t guess that you can turn off Grayscale in the zoom settings.

Turn off Colour Filters in Accessibility Shortcuts

Greyscale is actually a feature that can be accessed 3 ways and there’s actually another hidden place that you can access it from. With this on, Greyscale can even be accessed while you’re not in the settings app and you’re going to have to no idea how your iPhone just switched to ‘White and Black’ without you having a clue why it did this.

Above, I showed you both ways you can access Greyscale. With the Accessibility Shortcut on, if both the other Greyscale settings are turned off, you can still access Greyscale from here. To avoid this:

  • Launch the Settings app
  • Go to General
  • Tap on Accessibility
  • Tap on ‘Accessibility Shortcut’ right at the bottom
  • Make sure ‘Colour Filters’ are off

If this was on, if you accidentally clicked your home button three times, the Greyscale feature could have been accessed.

Why Greyscale was introduced

The main reason why Greyscale was introduced was to save battery. The normal colour that you see when you’re using your device is one of the main ways your battery gets drained. Since Greyscale only uses one shade which is grey, your battery power isn’t going to be spent on your LCD too much.

Since OLED displays are lit using individual pixels, pure black pixels draw no additional power. but even the slightest amount of colour will activate a pixel. Each pixel is made of subpixels for the colour. White or grey use all the subpixels.

So, if you took a solid red screen, only the red subpixels would be used. A solid purple would use all the blue and red subpixels. But a grayscale version of that screen would use a lower intensity of every subpixel on the screen which is why it saves battery.
