If you do not see this option

• Want a quick switch? Shortcut, at the bottom of the page, adds an on-off shortcut. Source: Use accessibility shortcuts
• Older OxygenOS? OnePlus's OxygenOS 14 manual puts Accessibility under Additional settings. Source: OxygenOS 14.0 User Manual

If this does not work

• Screenshots still in colour? That is normal: on ours the grey effect did not show in screenshots.
• Colours look odd after? Check Colour correction and Colour inversion are both Off on the Vision tab.

About this guide

Colour correction helps with colour blindness; Greyscale turns the whole screen grey.

The screenshots are from our OnePlus Nord 5 with OxygenOS 16.0.5.1201 and Android 16, in Dark mode. We switched on Greyscale, then off. Screenshots do not capture the grey, so our shot still shows colour.
