Hue Protection
How Hue Protection changes candidate ranking, when Dark Chroma Gate appears, and why Precise Colour Matching disables it.
Dark Chroma Gate
How the dependent Hue Protection threshold selects dark low-chroma candidates, what 0 means, and which matching paths read the value.
Auto Dynamic Range
How Lumina compresses source L* into the reachable brightness range of the active LUT or Material Archive, and when it skips the operation.
Isolated Pixel Cleanup
How Lumina identifies strict one-pixel recipe outliers, which neighbour value replaces them, and which conversion paths use the cleanup.
Precise Colour Matching
How LUT-constrained quantization keeps cluster centres inside the printer's reachable colour set and why it disables Hue Protection.
Model-Assisted Matching
Explains database-first, model-fallback, and model-only behaviour for native predictive colour sources.
Unlock Quantize Ceiling
How the switch raises the Quantize Colors ceiling from 256 to 8192, clamps the value again when disabled, and affects processing cost.
