The A200 has two custom white balance settings. You simply have to direct the camera to a white sheet of paper to record such a custom white balance. If you then use this custom white balance, there should be no color problems. Of course, you should make some tests before.
Overall the A200 image quality should be significantly better than the Z10, which had a much smaller sensor, no image stabiliser and a lower quality lense. Also unlike the Dimage Z series Minolta really did put its heart into the Dimage A series. Unfortunately they failed but it was not the quality of their cameras.
