Auto balance color on the R-D1 can sometimes be hit or miss. I have noticed that in one shot it can be quite good, in the next not. As has been stated, this is generally much more true indoors than out. OTOH, the specific color balance settings are excellent. If this really bothers you, you may have to keep twiddling the dial as light conditions change as you move around outdoors. This should really just be a problem on partly cloudy days. If its sunny or overcast, one setting should work for most of the day. Unfortunately, there's no easy way around this problem as you have presented it, but hey, that's what hobbies are for!
