I have a sure fired way of fixing this extreme color cast. Turn off the color calibration module in this case. Just use the white balance module and do a white balance based on a selected area. The white balance module will do a great job. Here is an example where I use this method on a crab photographed under red light. DT is the only program I know of that can do such a dramatic white balance fix. I have tried this image on many programs and only DT has ever worked for me.
EDIT: My method doesn’t work on the supplied image from the original poster. I will continue playing. But my method works for many images and is so easy. Just not this one.
