The ColorCorrect tool v2.0 will be released later today. Apart from the improved color matching capabilities of the algorithm, the new algorithm has a very much improved stabilization option, that allows for very good color matching, even if the source is noisy, or if the colors of the reference has inconsistencies. Here´s an example of matching the Star Wars bluray to a problematic frame of the technicolor IB reference print, with ColorCorrect v1.4, and ColorCorrect v2.0:
