To fix iPad Pro screen discoloration, first check settings: ensure **Invert Colors** and **Night Shift** are off in **Settings > Accessibility** and **Display & Brightness**. Restart your iPad by holding the power button, or perform a force restart if needed. Remove any cases or accessories that might interfere with the display. Update your software in **Settings > General > Software Update**. If discoloration persists, it may indicate a hardware issue. In that case, contact Apple Support or visit an authorized service provider for professional help. Use a protective case to prevent future damage.
