Using alpha/transparency in colors
My code sets the colour of an icon as follows:

```
    menu.findItem(R.id.action_notification).setIcon(new IconicsDrawable(this, FontAwesome.Icon.faw_android).
            color(R.color.iconactive).sizeDp(24));
```

Color is defined with a transparency component. However it still appears black on my app when I run it. Is this not supported then?

```
 <color name="iconactive">#36000000</color>
```
