Canon 70-200 continuous shots color shift problem. photographs pink

My first reaction on hearing this question was to suggest that it's a problem with lighting. I see this all the time when shooting in arena's because the light bulbs in arena's are often all different temperatures. Some give off a distinctly blue hue and others are definitely pink. The solution is to do your best to set the Kelvin temperature for your white balance or use your camera's method for automatically setting white balance. Just make sure you don't assume the ice is white, because it's not. And don't assume that all the light bulbs in the rink are the same. On our rink, some are distinctly blue and some are distinctly pink so no matter where I set my white balance, it is wrong some of the time.
