Disable 'Increase Contrast' in iOS Accessibility Settings

The primary cause of the blue background instead of the highlight color is the 'Increase Contrast' accessibility feature on your Apple device.

Apple's 'Increase Contrast' setting alters how apps display colors to improve readability. However, it overrides Microsoft Word's default highlight colors, causing them to render as solid blue blocks instead of translucent highlights.

1
Open Device Settings

Locate and open the Settings app on your iPhone or iPad.

2
Navigate to Accessibility

Scroll down the settings menu and tap on 'Accessibility'.

3
Access Display Options

Tap on 'Display & Text Size' under the Vision category.

4
Turn Off Increase Contrast

Find the 'Increase Contrast' toggle and switch it to the OFF position.

5
Relaunch Microsoft Word

Force close the Microsoft Word app by swiping up from the bottom of your screen, then relaunch it and try applying the highlight color again.

Frequently Asked Questions

Why does my iPad highlight in blue instead of yellow on Word?

This happens because the 'Increase Contrast' accessibility setting on your iPad overrides Microsoft Word's default highlight colors, causing it to display a solid blue background to enhance visibility. Disabling this setting in iOS Settings restores normal highlight colors.

Does uninstalling and reinstalling Word fix the highlight bug?

Usually, reinstalling the app will not fix this specific issue if the iOS 'Increase Contrast' setting remains enabled. You must disable the accessibility setting first for the highlight feature to function correctly.

Can I keep 'Increase Contrast' on and still use highlight colors in Word?

Currently, Microsoft Word's mobile app struggles to render standard highlight colors when 'Increase Contrast' is active on Apple devices. To see accurate highlight colors, you must temporarily turn off the contrast setting.

How do I change the highlight color in Word for iPad?

Select the text you want to highlight, tap the 'A' (Text Format) icon with a pen next to it in the home ribbon at the top of the screen, and choose your preferred color from the dropdown palette.
