The main issue is that the white balance off. I don't know if you were using AWB or not but I would recommend setting the white balance manually. If you were using flashes (looks light you were) then set it to 'flash' and the problem is solved. I always take manual control of the white balance. That way, even if the balance is off, there are no surprises and the results are consistent
Btw, Canon really needs to let us save more than one custom WB. What do most Nikon's allow? 5 or so?
