The focus point will flash green and the shutter release will be

pictures can be taken even when the focus point flashes red;
check focus in the monitor before shooting).

D Using Autofocus in Live View
Use an AF-S or AF-P lens.
The desired results may not be achieved
with other lenses or teleconverters. Note that in live view,
autofocus is slower and the monitor may brighten or darken while
the camera focuses. The focus point may sometimes be displayed
in green when the camera is unable to focus. The camera may be
unable to focus in the following situations:
• The subject contains lines parallel to the long edge of the frame
• The subject lacks contrast
• The subject in the focus point contains areas of sharply
contrasting brightness, or includes spot lighting or a neon sign or
other light source that changes in brightness
• Flicker or banding appears under fluorescent, mercury-vapor,
sodium-vapor, or similar lighting
• A cross (star) filter or other special filter is used
• The subject appears smaller than the focus point
• The subject is dominated by regular geometric patterns
(e.g., blinds or a row of windows in a skyscraper)
• The subject is moving
