The American Society of Cinematographers Colour Decision List (ASC CDL) colour correction specification defines a common language format for primary colour correction. It is becoming a standard defined by the ASC and has been adopted by most major manufacturers.
There are several types of implementations possible of the CDL. Lustre natively supports CDL as comments in a CMX 3600 EDL, which works for dailies workflow where you work with a colour management matching the final grading (this could include or not a film print emulation), the grading done at the dailies stage is recorded with the ALE that gets into the offline editor and documents the clips, then when you export the CMX in the EDL manager you enable the ASC-CDL in the comments and voilà, Lustre should be able to load the events from it in its assemble menu. IFFS supports the CDL note (one event) with its CDL Spark plugin.
CDL is expressed by nine numbers (three RGB triplets) representing predefined colour functions: offset, slope, and power. The format of CDL is standardized so results in one colour correction can be duplicated in another color grading system, so long as they both support the ASC CDL format. Currently, ASC CDL only supports primary colour correction and saturation.
