Just recently I was photographing a extreme red Geranium and got a very bad colour shift to the blue. Well is slept on this problem and the next day I decided to check the White Balance Setting. I photographed the same plant first in AWB then cascaded down through all the colour options. The day was cloudy and surprise of surprises the colour was tack on in the "Cloudy" setting, but still terrible on AWB.
So the conclusion I have come to is that with a very strong predominance of red the AWB is being thrown off toward the blue. I should have suspected this right off the bat as many algorithm tend to fall down under extreme conditions. The automatic balance like an averaging light meter works for the majority of times, but it is only a tool and it is up to the photographer to know when to use it and when not to use it . That being said , whenever possible, I will for not rely on the AWB. Finally the red colour shift that have bothered some with the Canon G1 is not a problem at all when you know your camera!
