Everything on your iPhone will now appear in only black and white coloring. If you're color blind, you can select the filter or tint that works best for your vision and adjust the levels accordingly. Interestingly, when you do a screen capture of grayscale, the resulting image is still colored. The picture immediately above is misleading because it shows grayscale turned on, but the screen is still colored. In actuality, it will appear gray as soon as you turn on the setting.
