I think Hammer has ruined Horror of Dracula by going this colder color route, as they ruined Curse of Frankenstein with a terrible transfer of a great hi-res scan. Hopefully they get it right with their upcoming release of The Mummy, which to me has always had some of the best and richest Technicolor examples.
Of course then there's also all the films with mis-registered 3 strip Technicolor, where nothing quite lines up and there are small color halos around everything.
