Use display and text size preferences on your iPhone, iPad and iPod touch
With iOS accessibility features for the display, you can enlarge your text, make it bold, increase the contrast, apply colour filters, use Smart Invert, control auto-brightness and more.
Display accessibility features are available on these devices:
Turn on Invert Colours
If you benefit from viewing items against a dark background, you can use Invert Colours to change how content is displayed on your screen.
To use Invert Colours, open the Settings app, then tap Accessibility > Display & Text Size. Turn on Smart Invert or Classic Invert.
Smart Invert
Smart Invert reverses the colours on the display, except for images, media and some apps that use dark colour styles.
Classic Invert
Classic Invert reverses all colours on the display.
Turn on Colour Filters
If you have colour blindness or other vision challenges, you can use Colour Filters to help you differentiate between colours. Colour Filters can change the way things look, such as pictures and films, so you may want to use it only when you need to.
Open the Settings app, then tap Accessibility > Display & Text Size > Colour Filters. You'll see three examples of colour spaces to help you select an option that fits your needs. Swipe left or right on the examples to find a filter that works best for you.
From left to right, this example shows pencils in a rainbow of colours, starting with red and yellow, and ending with purple and brown.
This example shows three columns of colour intensity.
This example shows vertical lines on a variable colour background for colour deficiencies. Choose the filter that shows the entire line.
Choose a filter
When you turn on Colour Filters, you can choose from four preset filters:
Greyscale
Red/Green for Protanopia
Green/Red for Deuteranopia
Blue/Yellow for Tritanopia
Adjust colour intensity
You can adjust the intensity of any of the Colour Filters to fit your needs. Use the Intensity slider to customise a filter that's more intense or less intense.
Adjust Colour Tint
If you have colour or light sensitivity, tap Colour Tint to change the hue of the entire display on your iPhone, iPad or iPod touch. Use the sliders to adjust your display's hue and the intensity of the effect.
