Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| channels | Choice | rgba | Which channels this node writes: rgba, rgb (alpha passes through untouched), alpha only, all, or none (bypass). Everything unselected comes straight from the input — same as Nuke. allrgbargbalphanone |
| value | Color | [0.0, 0.0, 0.0, 0.0] | Added to every pixel, per channel. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. | |
| hide_input | Bool | false | Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap). |
