There is a difference between the colors that people recognize and those that the camera recognizes, so colors will sometimes not be reproduced as expected. This often happens when the subject brightness is uneven or the subject is partially shaded. Change the shooting condition so that the subject is evenly exposed. This may also be solved by changing the Color, Brightness, White Balance, Exposure Value, or Exposure Comp. settings in the camera menu.
NOTE: Depending on the camera, when shooting in Intelligent Auto mode, it may not be possible to change the White Balance or Exposure Comp. setting when using the Partial Color feature.
