[Jason Jammer] “I really need consistency across all media platforms.”
The only way you can get close to color consistency is if you are making a movie that is graded in a proper suite and shown in theaters with calibrated projectors. There is zero way you can ensure consistency on the web because you can’t control how people have set up their monitors. Is it warm? Is it cool? Is it green?
