Thanks, I found the problem to be just as you noted. I had given the camera to a son to use and, being an experimenter, (and the recipient of my S3) he had changed many settings . I had overlooked WB in the menu. I now have it set to my liking at one dot to the left of center for auto. I used a white balance screen to manually set my Fuji Pro S3's for years.
I am about to experiment with setting the WB manually on the X using a screen and hand held meter. Thus far, the camera is quite interesting. I purchased it for travel and don't believe I will be disappointed.
