|:------------ |:-------------|:-----|:---|:---|
| In | Input | Vector 3 | None | Input value |
| Saturation | Input | Float | None | Saturation value |
| Out | Output | Vector 3 | None | Output value |
## Generated Code Example
The following example code represents one possible outcome of this node.
```
void Unity_Saturation_float(float3 In, float Saturation, out float3 Out)
{
float luma = dot(In, float3(0.2126729, 0.7151522, 0.0721750));
Out = luma.xxx + Saturation.xxx * (In - luma.xxx);
}
