The proof is in the pictures. The action can be downloaded from http://www.atncentral.com/download.htm#Kents_ColorcastFix for free, no registration or anything needed. They have tons of great free actions to download, some of which I use very frequently.
it seemed to work pretty well... there are options for selective enhancements once the action gets toward the end of being done but it creates an "average" color cast that you need to click once on and it removes said cast. then... it lets you tweak to suit. i did nothing selective on the example i posted.
