Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | — | |
| max_chroma | FLOAT | 5.00–50 | Below this mean chroma = monochrome. B&W scans <3, first real colour ~7. 0 disables detection. |
| sepia_max_chroma | FLOAT | 8.00–50 | Up to this chroma still counts as monochrome IF the hue is uniform (sepia / toned prints). |
| sepia_hue_spread | FLOAT | 0.450–3 | Circular hue spread below this = one dominant tint. |
| suffix_if_monochrome | STRING | _col | — |
| suffix_inopt | STRING | Prepended to the suffix output, so upstream tags (e.g. '_rev') survive. |
