Apple Color 1.5 - Manual (Page 51)

Once all your source media has been transcoded or captured as Apple ProRes 4444, it
can be imported into your Final Cut Pro project. If necessary, you can then create a
duplicate set of lower-resolution offline media with which you can edit your project more
efficiently.
Upon completion of the offline edit, you then relink the program to the original Apple
ProRes 4444 media before sending the sequence to Color, where you’ll be grading your
program. Ultimately, you’ll send the finished media that Color renders directly to the film
recording facility.
