Problem
A color-managed project is archived without its display transforms or custom LUTs, so the same timeline renders with visibly different color years later.
Solution
Root Cause / Diagnostic:
Modern color pipelines (ACES, DaVinci YRGB Color Managed, or custom LUT workflows) rely on external `.cube` lookup tables and exact input/output display transform configurations. If external LUT files and color management settings are omitted from the archive, reopened timelines revert to unmanaged raw log or mismatched gamma curves, destroying the creative color grade.
Actionable Fix:
1. LUT Bundling & Export: Package all custom `.cube` LUTs and 3D LUT tables into a dedicated `/COLOR/LUTS/` directory inside the project root folder.
2. Color Management Specification Documentation: Export a color decision list (CDL) and document exact timeline color spaces, working gamuts, and output transforms (e.g., ACEScc / Rec.709-A) in a project color sheet.
3. Graded Master Reference Export: Render a visually lossless reference file (ProRes 422 HQ) to serve as a side-by-side split-screen comparison against the restored timeline.
Pro Tip:
Always save your custom 3D LUTs inside the project archive folder; if your color management settings or LUTs are missing when you reopen the project, your footage will look flat, washed out, or wrong.
