It’s perfectly fine to add an attribute to note the color process used. Common examples are:
- (Metrocolor)
- (Eastmancolor)
- (Fujicolor)
- (Technicolor)
But please note that Technicolor was only a process until the mid-70s, after which they only processed Eastman/Kodak, so these should go to the technical list.
A mistake we often see is to add the name of the film laboratory as an attribute in the Color Info list. These should go to the technical list. Common examples of labs would be DeLuxe, Rank and Movielab.
Also note that in most cases we don’t accept episode level color data except where special episodes are different from the rest of the series.
