# particleColorBlendFactorSequence

The sequence used to specify the color blend factor of a particle over its lifetime.

```
var particleColorBlendFactorSequence: SKKeyframeSequence? { get set }
```

## Discussion

The default value is `nil`. If a non-`nil` value is specified, then the [`particleColorBlendFactor`](/documentation/SpriteKit/SKEmitterNode/particleColorBlendFactor), [`particleColorBlendFactorRange`](/documentation/SpriteKit/SKEmitterNode/particleColorBlendFactorRange), and [`particleColorBlendFactorSpeed`](/documentation/SpriteKit/SKEmitterNode/particleColorBlendFactorSpeed) properties are ignored. Instead, the sequence is used to specify the color blend factor.
