P Setting the Color Temperature
 When setting the color temperature for an artificial light source, set white
balance correction (magenta or green) as necessary.
 If you set [P] to the reading taken with a commercially-available color
temperature meter, take test shots and adjust the setting to compensate
for the difference between the color temperature meter’s reading and the
camera’s color temperature reading.
