Different color dropshadows ['red', 'green', 'blue']

Is it possible to make dropshadows different colors with an array? 

like this:

```
    dropShadow: {
      enabled: true,
      top: 0,
      left: 0,
      blur: 3,
      opacity: 0.5,
      color: ['red', 'green', 'blue']
    }
```
