If the subject is a traffic signal or electronic scoreboard, etc.,

Important
Since the light source selection options are based on
representative characteristics, proper colors may not be
achieved depending on the applicable light source. In this
case, use the [One-shot WB] function.
If the subject looks greenish under mercury lamps in the
[Auto] mode, select the [Mercury Lamp] mode under light
source. If the image is still not shown in appropriate colors
under mercury lamps when the [Mercury Lamp] mode is
selected under light source, use the [Auto] mode.
When the subject has only one color or when sodium lamps,
mercury lamps and certain other fluorescent lightings are
used, camera colors may not be adjusted automatically.
When [Day/Night] is set to [Night Mode] (including when it is
set to [Auto] and night mode is judged to be applicable), the
white balance function cannot be used.
Notes on capturing video continuously day and night
If a subject that seldom changes is captured in a location
where the light source changes gradually, such as when
capturing a subject continuously day and night, the image
may not be shown in appropriate colors.
In the above case, applying changes to the image to capture
will achieve the appropriate colors.
