If you’ve ever noticed your iPhone screen suddenly turn black and white, you’re not alone. Many iPhone users encounter this unexpected change and wonder what’s going on. In this guide, we’ll explain iPhone black and white mode (also called grayscale), how to enable it intentionally, and why it can be a helpful feature for some users. We’ll also cover troubleshooting tips and practical benefits.
What Is iPhone Black and White Mode?
iPhone black and white mode, also known as grayscale, turns your iPhone display into shades of gray instead of full color. It’s part of iOS’s Accessibility settings, designed to help users with visual impairments, but many people also use it to reduce distractions or save battery.
Key Points:
- Grayscale / monochrome display: All colors appear as gray shades.
- Difference from color mode: Apps, images, and videos lose their color palette.
- Benefits:
- Reduces eye strain for some users
- Helps focus by removing colorful distractions
- May slightly save battery on OLED iPhones
