Color differences-NBC NY vs NBC Burbank

[vallieone]

Anyone ever notice the difference in color transmission from programs originating from NBC New York vs NBC Burbank?

The New York colorcasts seemed to have a greenish tinge especially on dark haired individuals or black objects such as a piano. Examples are the video form Peter Pan, Bell Telephone Hour video clips etc.

The Burbank colorcasts had a purpleish or redish tinge to it as exampled by the Dean Martin Show and Laugh In shows.

Watching some of the old videos I can be pretty certain of the studio where it originated just by the color.

Anyone know why?
