A lookup table is a grade baked into a cube of colour samples: every input colour maps to an output one, so a whole film look travels as a single small file. Persona reads the two formats colour tools export — .cube and .3dl
Choosing One
Choose LUT… opens the Inventory under LUTs. Clicking a row applies it and closes; the button then names the table in use, with a bin button beside it to clear it
The LUT is active whenever a table is set — there is no separate switch. Intensity blends the graded frame against the ungraded one, from 0 (off in all but name) to 1 (the full table)
| Control | Range | Effect |
|---|---|---|
| Choose LUT… | — | Pick a .cube or .3dl table from the Inventory |
| Intensity | 0 – 1 | How far toward the graded frame to blend |
Where It Lands
The LUT runs after bloom and before colour grading, which is the order a colour pipeline expects: the glow is part of the image the table grades, and the parametric knobs are a correction on top of the look rather than something the look then re-maps
A table registered from a plugin folder that later leaves the disk shows as Missing — the grade stops applying and the frame renders ungraded rather than failing
