As the Google logo (shown here in white text) does not also have a pink colour-cast, it is highly unlikely that your iPad or screen hardware has a fault. If you had a colour-related display fault, you would almost certainly not see any white-text as an overlay.
As such, select a different wallpaper image:
Settings > Wallpaper > Choose a New Wallpaper
If changing your iPad wallpaper does not resolve the problem, you will need to check key Accessibility settings that are intended to compensate for specific colour-vision issues:
Settings > Accessibility > Display & Text Size
Ensure that all settings enclosed within the red box above are switched OFF/Disabled.
