In doing additional research I’ve found two additional methods to accommodate hue contamination. This is geared toward Ps users. However, I'm sure other processing software has similar methods. Each method produces a slightly different solution to hue contamination.

Method 1:
Open the image. In the Image pull-down menu select Adjustment, then Match Color. Finally, check the box in the popup window that is labeled Neutralize.

Method 2:
Open the image. In the Image pull-down menu select Auto Color

These two methods, along with the process described in the mentioned article each produce slightly different results. In some cases, the results may not be satisfactory. So, now we have three methods to accommodate hue contamination.

I’ve attached each of the original versions of the images used in the article. So, those of you who use Ps can experiment.

So I tried both of these methods with the deer, and both gave me a blue-puprle-ish tint to the deer's nose and other areas. Doesn't seem like a giant step forward. What am I missing?

Actually, these images were used with the permission of those who took them. I felt they were good examples of hue contamination of color cast.

I appreciate your compliment, but definitely don't want to take credit for something that isn't mine.

These kinds of questions are difficult to answer due to the various possibilities of monitor calibration, etc. Additionally, if you refer to the original post, you see that these adjustments are gross overall adjustments. I stated that some additional tweaks might be necessary.
