# SCNParticleBlendMode

Options for combining source and destination pixel colors when compositing particles during rendering, used by the [`blendMode`](/documentation/SceneKit/SCNParticleSystem/blendMode) property.

```
enum SCNParticleBlendMode
```

## Topics

### Constants

[`SCNParticleBlendModeAdditive`](/documentation/SceneKit/SCNParticleBlendMode/additive)

The source and destination colors are added together.

[`SCNParticleBlendModeSubtract`](/documentation/SceneKit/SCNParticleBlendMode/subtract)

The source color is subtracted from the destination color.

[`SCNParticleBlendModeMultiply`](/documentation/SceneKit/SCNParticleBlendMode/multiply)

The source color is multiplied by the destination color.

[`SCNParticleBlendModeScreen`](/documentation/SceneKit/SCNParticleBlendMode/screen)

The source color is added to the destination color times the inverted source color.

[`SCNParticleBlendModeAlpha`](/documentation/SceneKit/SCNParticleBlendMode/alpha)

The source and destination colors are blended by multiplying the source alpha value.

[`SCNParticleBlendModeReplace`](/documentation/SceneKit/SCNParticleBlendMode/replace)

The source color replaces the destination color.
