Dark neutral | 32 / 32 / 32 | Check shadow tint | Observed: __________ | Next decision: __________
Mid neutral | 128 / 128 / 128 | Check colour cast | Observed: __________ | Next decision: __________
Near white | 240 / 240 / 240 | Check clipping and tint | Observed: __________ | Next decision: __________
Purple accent | 111 / 74 / 210 | Check hue and saturation shift | Observed: __________ | Next decision: __________

Review steps:
1. Open Grade with a source and reference image. Start with a restrained transfer amount and compare the split preview.
2. Inspect neutrals and the important subject separately. A look that suits a landscape may shift a face or product colour unhelpfully.
3. Export a test PNG or available cube LUT and try it in the actual destination. Keep an untreated original and record the amount used.

Decision note: This chart offers specific comparison points, not a measured Grade result. A LUT is not relighting, exposure repair or a promise of matching across cameras. Check the destination colour pipeline before adopting it.
