Right, if you incorrectly specify Incandescent white balance in daylight outdoors, the pictures will be extremely blue.
Use Daylight white balance if in sunlight. Or maybe Cloudy or Shade white balance if more applicable.
Or, if shooting Raw, you can simply correct it later.
thats it, i have did this twice and Don always pointed it out, probably changed it for indoors and forgot to switch back, at least you spotted it, i never did. lol
