ColorCorrect
Colorv2coreConcat: Pointwise
Overview
Colour correction in zones: master, shadows, midtones and highlights each get their own saturation/contrast/gamma/gain/offset — grade the tones separately.
How to
How-to
- The master controls apply everywhere; the
shadows,midtonesandhighlightspages apply their own settings in that tonal zone. - Start with saturation and contrast on the master, then open the shadows page to lift or cool them alone.
- A
masklimits the whole node.
Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |
Outputs
| Output | Type |

| out | Image |
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 |
| saturation | Float | 1.0 | Colour intensity: 0 = grayscale, 1 = unchanged. |
| contrast | Float | 1.0 | Stretches (>1) or flattens (<1) the range around mid-grey. |
| gamma | Color | [1.0, 1.0, 1.0, 1.0] | Bends the midtones with a power curve; ends stay put. |
| gain | Color | [1.0, 1.0, 1.0, 1.0] | Multiplies the signal — the main brightness/strength control. |
| offset | Color | [0.0, 0.0, 0.0, 0.0] | Adds a constant to every pixel. |
| shadows_saturation | Float | 1.0 | The same control, applied only in the shadows (weighted by darkness). |
| shadows_contrast | Float | 1.0 | The same control, applied only in the shadows (weighted by darkness). |
| shadows_gamma | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the shadows (weighted by darkness). |
| shadows_gain | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the shadows (weighted by darkness). |
| shadows_offset | Color | [0.0, 0.0, 0.0, 0.0] | The same control, applied only in the shadows (weighted by darkness). |
| midtones_saturation | Float | 1.0 | The same control, applied only in the midtones. |
| midtones_contrast | Float | 1.0 | The same control, applied only in the midtones. |
| midtones_gamma | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the midtones. |
| midtones_gain | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the midtones. |
| midtones_offset | Color | [0.0, 0.0, 0.0, 0.0] | The same control, applied only in the midtones. |
| highlights_saturation | Float | 1.0 | The same control, applied only in the highlights (weighted by brightness). |
| highlights_contrast | Float | 1.0 | The same control, applied only in the highlights (weighted by brightness). |
| highlights_gamma | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the highlights (weighted by brightness). |
| highlights_gain | Color | [1.0, 1.0, 1.0, 1.0] | The same control, applied only in the highlights (weighted by brightness). |
| highlights_offset | Color | [0.0, 0.0, 0.0, 0.0] | The same control, applied only in the highlights (weighted by brightness). |
| 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). |
