Gets or sets a lightness modifier.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public float Lightness { get; set; }
```
 
### Property Value
The lightness modifier value in range [-1, 1]. The default value is `0`.
 
## Remarks
 This parameter allows to change intensity of the color. It works similar to [Brightness](https://www.graphicsmill.com/docs/gm/T_Aurigma_GraphicsMill_Transforms_Brightness.htm.md) transform, however another algorithm is used and result differs from brightness adjustment.
